Krix UCX-118
The grand debut of Krix UCX-118 in Malaysia
The Krix UCX-118 is a high-performance infrasonic subwoofer designed for serious home cinema enthusiasts who want bass they can not only hear but physically feel. It made its international debut at CEDIA Expo 2026, where it won a "Best of Show" award in the Residential Systems category. Infrasonic bass refers to sound waves that vibrate at a frequency below the human hearing threshold, typically under 20 Hz. While you cannot hear infrasonic bass as a distinct tonal sound, you can feel it physically as vibrations against your skin, chest, and through the floor or furniture. In home cinemas, it provides the intense, tactile pressure felt during deep explosions, rocket launches, or earthquakes.
At the heart of the UCX-118 is a single 18-inch (460mm) high-excursion driver. This driver features a treated paper cone, a 4-inch voice coil, a neodymium magnet, and a demodulating ring to keep distortion low even at high output levels. The result is a subwoofer that extends deep into the infrasonic range, delivering the tactile rumble and impact that makes movie soundtracks feel truly cinematic.
The UCX-118 is a passive subwoofer, meaning it requires external amplification and digital signal processing (DSP). Krix offers optimized DSP presets for use with its own amplifiers, such as the KA-1000X4 and KA-27000X4, ensuring the driver performs exactly as intended. A key design advantage is its compact cabinet depth of just 321mm. This shallow profile makes it much easier to integrate multiple units into a room, whether built into a riser, behind an acoustically transparent screen, or placed in a dedicated equipment space.

Krix UCX-118
The Krix UCX-118 is a premium, high-output 18-inch passive infrasonic subwoofer engineered specifically for high-end home cinema installations. Part of Krix's professional-grade cinema lineup brought into the residential space, it is designed to deliver deep, tactile low-frequency extension down to 10Hz when paired with appropriate digital signal processing.
Designed and manufactured in Adelaide, South Australia, the Krix UCX-118 subwoofer is an award-winning, compact passive infrasonic subwoofer engineered to deliver tactile, cinema-grade bass. It features a single 460mm (18-inch) high-excursion treated paper cone driver with a 100mm voice coil, a neodymium magnet, and 50mm peak-to-peak displacement to reproduce deep frequencies ranging from 10Hz to 200Hz (with DSP). Requiring external amplification and DSP (such as compatible Krix or partner amplifiers), the 4-ohm, 34kg enclosure handles up to 1,250 Watts continuous and 5,000 Watts peak power, making it ideal for standalone use or multi-subwoofer setups in dedicated home theaters.
The Krix UCX-118 blends excellently with Krix speaker lineup by acting as a unified extension of the system's low-frequency response. Rather than requiring separate subwoofers for chest-thumping mid-bass and deep infrasonic rumbling, its wide frequency range (10Hz–200Hz) allows it to seamlessly hand off frequencies directly to main cinema channels. Because it uses similar high-velocity treated paper cone tech found in Krix main speakers, the driver speeds and tonal characteristics match perfectly. Krix provides specialized DSP configuration files engineered for their partner amplifiers, including the Krix KA-1000X4 and KA-2700X4. These presets precisely align the subwoofer's phase, crossover slope, and time-delay with Krix main speakers like the Series MX modular systems or Megaphonix and Hyperphonix series.
Building a dedicated home cinema around Krix gives you true commercial-grade dynamics and infrasonic bass, as their residential speakers are scaled down directly from their professional movie theater systems. The UCX-118 is engineered to scale easily into multi-sub arrays, such as double bass arrays or waveforming setups). In an all-Krix setup, this creates a uniform wavefront of low-frequency energy that tracks the exact speed and impact of the main soundstage, eliminating localized "boomy" spots. To hit 10 Hz in a Krix home cinema, you will want to pair one of their horn-loaded front stages with their passive infrasonic subwoofers and dedicated DSP amplification.
For a dedicated room with an acoustically transparent screen, Krix’s modular Series MX wall systems are the gold standard. They bolt together into a solid infinite baffle wall with acoustic foam fronts to eliminate sound reflections behind the screen. Krix MX-30i or MX-40i. Krix upgraded their flagship modular walls specifically for infrasonic output. Both the Krix MX-30i, for medium-to-large rooms and MX-40i, for large rooms up to 14 meters deep, pair three horn-loaded LCR speakers with two MXi-118 18-inch infrasonic subwoofer modules rated down to 10 Hz. For floorstanding loudspeaker behind your screen instead of a modular wall, the Krix Theatrix uses a 15-inch mid-bass driver and commercial horn tweeter (96 dB sensitivity) capable of keeping pace with dual 18-inch subwoofers.
Krix UCX-118 commercial-grade infrasonic series is explicitly rated down to 10 Hz. Built around massive 18-inch drivers (single in the UCX-118, dual in the UCX-218). Human hearing stops around 20 Hz, so frequencies down to 10 Hz are felt physically as air pressure and tactile rumble rather than heard. Achieving clean 10 Hz output at high volume requires massive air displacement)

Krix Theatrix
The Krix Theatrix is a top tier home cinema loudspeaker, with an incredibly sensitive speaker (96dB @ 1m) capable of continuous, massive sound pressure levels with virtually zero distortion. Unlike brands like KEF, Monitor Audio, Focal, DALI or Wharfedale, which started in traditional two-channel consumer stereo hi-fi, Krix’s modern identity is hardwired directly into commercial cinemas. Over 4,000 commercial movie theaters globally utilize Krix horn-loaded loudspeaker systems. When they design residential gear, they scale down actual commercial-theater components rather than scaling up small living room speakers.
Pairing the Krix Theatrix 3-way cinema speakers with two units of the Krix UCX-118 subwoofers creates an absolute powerhouse system. This configuration mimics a commercial cinema setup, combining high-sensitivity, horn-loaded dynamics with massive, infrasonic low-frequency authority. Because it uses a large 15-inch mid-bass driver and a horn-loaded midrange/tweeter array, it can effortlessly keep pace with the punishing output of two massive 18-inch infrasonic subwoofers. Your main speakers will never feel "drowned out" by the bass; instead, you get a cohesive wall of sound.
While the Theatrix is rated down to 38Hz in-room, a dual UCX-118 setup allows you to offload the heavy lifting. Setting a crossover around 60Hz to 80Hz relieves the main 15-inch drivers on the Theatrix from reproducing deep bass. This drastically cleans up the midrange vocals and mid-bass punch on your main channels. The dual UCX-118s handle everything from the crossover point all the way down to 10Hz, giving you both physical impact and pristine dialogue clarity.
Using two UCX-118 units rather than one is highly advantageous for an extreme system like this. Bass frequencies create standing waves (room modes) that result in "dead zones" where bass disappears or "boomy zones" where it overpowers the room. Placing two subwoofers strategically (e.g., flanking the Left and Right channels, or centered at the 1/4 and 3/4 points of the front wall) naturally smooths out those peaks and nulls. Running dual subs gives you up to a 6dB increase in headroom. The subwoofers can achieve the same target volume while moving half as much, meaning lower distortion and completely effortless infrasonic pressure. The Krix Theatrix handle up to 500W RMS. High-end cinemas frequently run them in bi-amp mode using heavy-duty multi-channel amplifiers like StormAudio power amplifiers to power the low-frequency and mid/high horn assemblies independently.
For the UCX-118s, they require dedicated external amplification with custom DSP. A dual configuration is perfectly paired to a single Krix KA-27000X4 amplifier utilizing Krix’s pre-configured DSP safety and tuning maps.
Watching A Quiet Place on a system with Krix Theatrix mains and dual Krix UCX-118 subwoofers would be an absolutely terrifying, masterclass cinema experience. Because that movie relies entirely on the contrast between absolute silence and sudden, violent sound, this specific gear combination is uniquely equipped to deliver exactly what the directors intended. Here is how it would actually feel to watch it. In A Quiet Place, silence isn't just the absence of sound; it's a physical presence. The high sensitivity of the Theatrix horns means you will hear the microscopic details of the environment, the rustle of corn leaves, footsteps on sand, or a sharp intake of breath, with absolute, lifelike clarity. And the there are the Infrasonic Pressure. Even when the movie is seemingly silent, the dual UCX-118s will often be reproducing ambient room tones or ultra-low frequency thrums below 20Hz. You won't hear a "bass note," but you will feel a heavy, suffocating pressure in the room that spikes your adrenaline and creates a genuine sense of dread. The "Jump Scares" Will Shake You Physically. When a sound is made—like the accidental dropping of a toy or the clatter of a lantern, the transition from dead silence to explosive sound is where this system shines. The Krix Theatrix is like a supercar with instant dynamic impact is, because the speakers can go from 0 to 100 instantly without compressing the audio, a sudden scream or crash will make you jump out of your seat. The moment a creature attacks, the dual 18-inch UCX-118s will hit you with 10Hz to 30Hz energy. This is clean and pristine cinema grade bass, it is a violent, structural vibration. The impact will physically hit your chest, shake your couch, and make you feel like the creature is breaking into your actual room.
In short, it wouldn't just feel like watching a movie; it would feel like an intense, highly immersive simulation where you are afraid to make a sound in your own theater. Visit our showroom to experience the immersiveness of 16 channel cinema comprising of Theatrix, dual UCX-118 and other Krix speakers.
Krix is famous for pioneering the MX Series "Wall of Sound" modular, architectural speaker systems designed to be permanently built into a false wall completely behind an acoustically transparent projector screen. Because their high-performance lines are designed for custom installation, architectural integration, or on-wall theater setups, they aren't typically sold box-ready on standard retail floors alongside plug-and-play living room gear. If you are looking to build a high-SPL (Sound Pressure Level), high-efficiency home theater with massive dynamics, a flawless identical LCR front soundstage, and zero distortion at extreme volumes, Krix is a top-five contender globally.

Krix MX40
The Krix MX-40 is the flagship modular front-stage speaker system in Krix's Series MX line, engineered in Australia to sit behind an acoustically transparent screen in large dedicated home cinemas. Designed for rooms measuring 5 to 14 meters in depth, the five-module system spans 3,165 mm wide by 1,220 mm high and 335 mm deep, with each individual cabinet weighing 65 kg.
The Krix MX-40 combines three identical left, center, and right (LCR) speaker modules with two dedicated subwoofer modules to create an infinite baffle wall of sound. The LCR cabinets mark the first 3-way, bi-ampable design in the Series MX range and require an active crossover set at 400 Hz. Each LCR module houses a 380 mm (15-inch) high-stiffness paper cone bass driver alongside Krix's proprietary 90° by 40° single-mould dual horn, which pairs a 152 mm (6-inch) midrange driver with a 35 mm (1.4-inch) high-frequency compression driver. This horn architecture maintains uniform directivity and low distortion even at extreme commercial cinema sound pressure levels. For deep bass impact, each of the two front-vented bass reflex subwoofers incorporates a 455 mm (18-inch) paper cone driver with a 100 mm edge-wound copper voice coil.
The LCR modules deliver a 38 Hz to 16 kHz frequency response with high sensitivity ratings of 98 dB (low-frequency) and 101 dB (high-frequency horn), handling 100–700W RMS and 100–400W RMS respectively at an 8-ohm impedance. The subwoofers extend from 25 Hz to 200 Hz with 100 dB sensitivity and handle 200–1,400W RMS using a recommended 20 Hz high-pass filter and 1,000-watt limiter
All five cabinets share unified height and depth dimensions, feature internally X-braced 18 mm MDF construction in Cinema Black, and utilize concealed front-mounted spring terminals for front-side wiring access. Krix advises pairing the setup with a screen size of at least 145 inches for 16:9 or 140 inches for 21:9 scope formats.
The Krix MX-40 delivers commercial-cinema dynamics, ultra-low distortion at reference volume, and seamless soundstage uniformity across wide seating rows. Built around a true 3-way bi-amplified front stage, it avoids the midrange strain common in smaller 2-way theater speakers while preserving crisp vocal clarity behind acoustically transparent screens.
Unlike 2-way theater systems that force compression drivers low into the vocal range, the Krix MX-40 relies on a dedicated 152 mm (6-inch) paper cone midrange driver to handle frequencies starting at 400 Hz. Isolating vocal fundamentals from the heavy excursion of the 15-inch bass drivers keeps speech natural, uncolored, and completely intelligible even during chaotic action sequences. Because the 35 mm (1.4-inch) titanium compression driver only engages in the upper treble register, high-frequency details remain crisp and airy without ever sounding harsh or fatiguing during long movie marathons.
Installing all five modules flush across the front wall forms an infinite baffle that eliminates rear-wall acoustic cancellations, delivering a tight, punchy upper-bass response. The proprietary 90° by 40° constant-directivity dual horn spreads audio evenly across wide multi-row seating while restricting vertical bounce off the floor and ceiling. This controlled dispersion locks imaging onto the screen so that every seat in the room enjoys a consistent, enveloping front wall of sound where pan transitions between left, center, and right channels feel completely invisible.
With ultra-high sensitivity ratings of 98 dB to 101 dB, the system effortlessly reaches commercial theater reference volumes with massive headroom to spare. During explosive blockbusters, the combination of three 380 mm (15-inch) LCR drivers and dual 455 mm (18-inch) front-vented subwoofers delivers visceral, fast-decaying chest slam down to 25 Hz. Heavy-duty voice coils and vented magnet assemblies prevent thermal compression, allowing the Krix MX-40 to pivot instantaneously from whisper-quiet atmospheric tension to thunderous dynamic peaks without strain.
Pairing the Krix MX-40 with a dual Krix UCX-118 subwoofers extends the system's low-frequency reach into the infrasonic 10 Hz range, adding visceral sub-25 Hz physical pressurization to the MX-40's commercial-grade mid-bass slam. Because the standard MX-40 package already includes two 18-inch front-vented subwoofers tuned down to 25 Hz, adding dual UCX-118 units either operates as a four-subwoofer multi-zone array for superior room-mode smoothing or replaces those front modules to create an MX-40i style infrasonic front wall.
The standard Krix MX-40 subwoofers use a bass-reflex design engineered for high-sensitivity (100 dB) mid-bass punch down to 25 Hz, whereas the Krix UCX-118 utilizes a sealed high-excursion 460 mm (18-inch) neodymium driver with 50 mm peak-to-peak displacement that reaches down to 10 Hz with DSP. With high-sensitivity 3-way LCR modules rated at 98 dB to 101 dB, the MX-40 front stage easily keeps pace with the massive output of dual UCX-118s without vocal dialogue ever sounding drowned out. Crossing the main LCR modules over between 60 Hz and 80 Hz offloads deep bass from the three 15-inch mid-bass drivers, keeping midrange dialogue pristine while the dual UCX-118s pressurize the room during explosions, low-frequency rumbles, and seismic movie effects.
Keeping the MX-40's two front-wall bass-reflex subwoofers in place while positioning the dual Krix UCX-118 units at the rear of the room creates a four-subwoofer front-and-back array that evens out standing waves across multiple seating rows. Measuring 665 mm high by 650 mm wide and just 321 mm deep at 34 kg each, the UCX-118 cabinets fit discreetly inside rear false walls, behind acoustic fabric panels, or alongside seating rows without intruding into the room. Alternatively, if you have not yet purchased the full five-module MX-40 package, pairing just the three MX-40 LCR modules with dual UCX-118s mirrors Krix's MX-40 concept, though the shorter 665 mm UCX-118 cabinets will require framing into the front baffle wall to match the 1,220 mm height of the LCR modules.
Unlike the 8-ohm MX-40 subwoofers, each Krix UCX-118 is a passive 4-ohm subwoofer rated for 1,250W continuous (2,500W program / 5,000W peak) and requires external amplification with Krix-optimized DSP presets to achieve its flat 10 Hz to 15 Hz extension safely. Krix specifies pairing them with dedicated DSP amplifiers such as the Krix KA-2700X4 (4 × 2,700W at 4 ohms), the Krix KA-1000X4 (bridged to 2 × 2,700W at 4 ohms), or approved Powersoft and Connect 1504 DSP platforms. Furthermore, because combining ported MX-40 subwoofers with sealed UCX-118 subwoofers introduces different phase and group-delay behaviors, proper time alignment and phase calibration via an advanced processor like Trinnov, StormAudio, or Dirac Live Bass Control is essential so all four subwoofers sum cleanly rather than canceling each other out.

Krix MX-30I
The Krix MX-30i is a high-performance, modular three-way home cinema speaker system specifically engineered for large dedicated theater rooms. It functions as a complete "wall of sound" designed to sit directly behind an acoustically transparent projection screen, mimicking the exact structural design used in commercial movie theaters. The system consists of three identical screen speaker modules for the left, center, and right channels, coupled with two massive passive subwoofer modules that fit together into a cohesive single line.
Krix MX-30i is horn-loaded. A defining engineering feature of this system is the proprietary Krix horn design. The main screen channels utilize a heavily optimized horn system paired with compression drivers, which enables the system to deliver exceptionally high efficiency, low distortion, and uniform coverage across every seat in the room. This ensures that movie dialogue remains crystal clear, and dynamic sound effects hit with immediate impact even at high volumes. Specifically, the three main Left, Center, and Right (LCR) screen modules in the system utilize Krix’s proprietary 90-degree by 40-degree short-throw constant-directivity horn.
This horn structure is paired with a high-performance 35mm (1.4-inch) compression driver to handle the high frequencies and midrange details. The large 15-inch bass driver sits below the horn to handle the mid-bass frequencies.
The Krix MX-30i is a massive, modular front-wall home cinema system engineered for large dedicated theater rooms. It acts as a discrete "wall of sound" positioned directly behind an acoustically transparent projection screen to replicate commercial cinema audio dynamics.
The "i" (Infrasonic) revision keeps Krix’s high-performance Left-Center-Right (LCR) modules unchanged but completely overhauls the subwoofer components. It replaces the older subwoofers with new 18-inch infrasonic drivers and a newly engineered, reversible cabinet layout that allows installers to rotate the subwoofers 180 degrees to optimize bass placement in the wall.
The total system is comprised of five interlocking modules (three LCR screen speakers and two passive subwoofers) that align flush into a singular baffle wall. [1]
Total Assembled Dimensions: 1,220mm High × 2,865mm Wide × 335mm Deep
Total Assembled Weight: 254 kg total (Three LCRs at 48 kg each + Two Subwoofers at 55 kg each).
Enclosure Profile: Extremely shallow depth (335mm) specifically engineered to fit tightly inside framed false-wall cavities without eating up room length.
Baffle Face: The front surface of all modules is completely layered with specialized acoustic absorption material to stop high-frequency audio reflections behind the projection screen.
These modules handle dialogue, panning, and the primary soundstage. Key specs include a 2-way crossover network, a Krix 90° x 40° short-throw constant-directivity horn with a 35mm compression driver, and a single 380mm (15”) low-frequency driver. They feature a frequency range of 38 Hz to 16 kHz, a recommended amplifier power of 100 to 700 Watts RMS, a sensitivity of 98 dB, and an 8-Ohm nominal impedance.
The passive subwoofers are designed for deep, tactile low-frequency output. Each includes a 460mm (18”) treated paper cone driver with a 100mm voice coil and neodymium magnet assembly, delivering a 50mm peak-to-peak linear excursion. They cover a frequency range of 10 Hz to 200 Hz with DSP (reaching down to 13 Hz at -6dB), require 1,500 to 3,000 Watts RMS of amplifier power, offer a 100 dB sensitivity with a 4-Ohm impedance, and feature a dual-terminal plate for a 180-degree cabinet flip to optimize room boundaries.
To power the uncompromising Krix MX-30i system, choosing the right combination of amplification and processing is critical. While StormAudio makes some of the finest home cinema processors and multi-channel amplifiers on the market, the sheer power requirements of the MX-30i subwoofers mean you will likely want a hybrid layout rather than a single-brand approach.
StormAudio is a premium option for managing this tier of cinema. However, you must carefully divide their hardware based on the channels they are driving.
For the LCR Channels: A multi-channel amplifier like the Storm Audio PA 8 Ultra MK3 or PA 16 MK3 is an outstanding choice. These utilize high-end Class D modules capable of delivering 200 Watts continuous into 8 Ohms (and up to 400 Watts into 4 Ohms). This provides pristine, low-distortion power with an incredibly low noise floor, making movie dialogue through the MX-30i main horns completely transparent.
To power the massive 18-inch drivers of the MX-30i infrasonic subwoofer modules, we highly recommend Krix's heavy-duty high-power X4 series amplifiers.
The two Krix amplifier models built to satisfy the 1,500W to 3,000W RMS power requirement are:
Krix KA-2700X4: This is the ideal single-chassis match. It provides a staggering 2,700 Watts RMS per channel into 4 Ohms across four channels. You would use two of the channels to drive your two MX-30i subwoofer modules, leaving two channels completely free to power additional surround subwoofers or tactile transducers later.
Krix KA-1000X4 (Bridged): While this model outputs 1,000 Watts per channel into 4 Ohms in standard mode (slightly under the target), it can be custom-bridged into a 2-channel configuration. Bridging it combines the internal channels to deliver a matching 2,700 Watts RMS into 4 Ohms per subwoofer module.
Both options come pre-loaded with Krix's custom 24-bit DSP ecosystem, which automatically applies the precise voltage limiting and the 10Hz subsonic high-pass filters needed to protect these massive 18-inch cones from over-excursion.
Now let's talk about the sound quality. The sonic signature of the Krix MX-30i is best described as effortlessly natural, completely transparent, relentless, and violently dynamic. Because it utilizes the exact design principles found in commercial cinemas but scales them down into a controlled residential environment. The experience is fundamentally different from a traditional high-end home theater setup.
The sound quality and immersion you experience with this system stand out in several distinct ways. The high sensitivity of the system, 98dB on the mains and 100dB on the subwoofers means it requires very little effort to get incredibly loud. It is a good for your neighbors to make friends with you. When an explosion, gunshot, or sudden musical crescendo occurs on screen, the sound hits you instantly. There is no electronic straining, no compression, and none of the harsh, piercing treble that often plagues cheap theater setups at high volume. The system handles massive cinematic scale just as easily at reference volume as it does during quiet scenes.
Did we mention effortlessly natural? Flawless dialogue clarity because the Left, Center, and Right (LCR) modules are completely identical and use professional grade constant directivity horns, the front soundstage is seamlessly unified. Dialogue is anchored perfectly to the screen. Even during intense action sequences with heavy background music and sound effects, voices remain crisp, articulate, and completely intelligible. The high-frequency compression drivers reproduce the subtle textures of a human voice without ever sounding clinical or artificial.
Here is why your neighbours kept coming over. The transition to the 18-inch infrasonic subwoofers completely changes how you experience bass. This system doesn't just make a "booming" sound; it alters the atmospheric pressure in the room. Because it extends cleanly down to 10Hz–13Hz, it reproduces the subsonic frequencies that you cannot hear with your ears but physically feel in your chest and seat. The bass is incredibly fast, tight, clean and stops on the dot, providing the visceral impact of an earthquake or rocket launch without any muddy overhang.
When installed behind an acoustically transparent woven screen, the physical speakers completely disappear from your conscious mind. The massive acoustic absorption material covering the front baffle stops sound from reflecting off the back of the screen fabric. This results in a massive, sweeping wall of sound where audio pans seamlessly across the room. You don't hear speakers sitting in a corner; you simply experience a soundstage that perfectly tracks the action moving across the visual frame.
Watching A Quiet Place on the Krix MX-30i is an exercise in absolute tension because the system handles near-total silence just as powerfully as it handles sudden, terrifying noise. The film relies heavily on a stark, minimalist sound design, and the MX-30i transforms that audio track into a visceral physical experience in several specific ways.
In a movie where characters survive by remaining silent, the background ambient noise becomes a character itself. Through the MX-30i, the absolute quiet of the post-apocalyptic world feels heavy and atmospheric. Because the horn-loaded compression drivers are incredibly efficient and driven by high-end external amplification, the system has a microscopic noise floor. You hear the absolute finest details with pristine clarity, the soft crunch of sand under bare feet, the rustle of leaves in the wind, and the anxious, shallow breathing of the characters. These tiny sounds don't get lost; they hang realistically in the room, drawing you deep into the family's isolation.
The true power of this system lies in its dynamic range, the ability to jump from absolute zero to maximum volume instantly. When someone accidentally drops an object or makes a sound, the sudden noise doesn't just sound loud, it hits with the FORCE of a physical jump scare. Because the LCR modules have massive power headroom, the sudden crash or scream has an immediate, sharp impact without a hint of distortion or electronic clipping. It perfectly mimics the biological panic the characters feel, forcing a genuine adrenaline spike. Now your neighbours are sharing your pop corn.
When the creatures are hunting, their heavy footsteps and clicking sounds pan across the front wall with terrifying precision. The identical LCR modules create a flawless, seamless soundstage behind the screen. As a monster moves from left to right, you can trace its exact path blindly. The clicking sounds of the creatures' armor plating open up with a crisp, hard-edged texture that sounds menacingly real and physically close. The deep immersiveness transported your mental state (and your neighbours) into the movie scene.
When the creatures reveal themselves or roar, the transition to the 18-inch infrasonic subwoofers elevates the fear. The creatures' heavy thuds and low-frequency growls drop straight into the 10Hz to 15Hz range. You don’t just hear a bass tone, the air pressure in your cinema room changes. Your seat vibrates, and a deep, heavy pressure hits your chest. This subsonic weight makes the monsters feel massive, dense, and physically present in the room with you. You looked over your shoulder, screaming RUN! in your mind.
Ultimately, it stops feeling like you are watching a movie track and feels like you are trapped in the room with the characters, holding your breath alongside them. The MX-30i is the smart engineering choice, hides completely behind a screen, takes up minimal space, and gives you a brutal wall-of-sound effect out of a single box.
If you have a deep room that can sacrifice over half a meter of length to a massive custom baffle wall, the Krix Theatrix + Dual UCX-118 combination represents the higher acoustic ceiling. The 3-way horn architecture provides stunning midrange purity for dialogue and musical scores, while the standalone subwoofers allow us to fine tune your bass response perfectly to the room's unique geometry.
The Krix MX-30i requires a serious commitment to room planning, professional installation, and proper multi-channel amplification to achieve its full potential. It is an uncompromising choice built for audiophiles and cinema enthusiasts who want absolute commercial-grade theater dynamics and sonic accuracy duplicated inside their homes.

Krix MX-20
Engineered specifically for medium-sized dedicated cinema rooms, the mid-tier Krix MX-20 is a precision crafted, five-module front stage designed to disappear completely behind a screen. Inside a clean, flush-mounted front baffle wall sit three dedicated left, center, and right main speakers paired with two formidable passive subwoofers—creating an invisible, unified wall of acoustic power.
System Design & Installation
Modular Wall of Sound. The system includes five separate cabinets sharing an identical height of 1220 mm and a slim depth of 295 mm. Placing them side by side creates a total width of 2210 mm without optional spacer panels.
Acoustic Treatment. Each module features a thick acoustic-absorbent front baffle. This design mimics Krix's commercial cinema Infinite Baffle Wall to eliminate sound reflections off the back of the projection screen.
Room & Screen Sizing. Krix recommends the MX-20 for rooms measuring 4 to 7 meters in length. It requires an acoustically transparent screen with a minimum size of 105 inches (16:9) or 130 inches (21:9)
The original MX-20 uses a dome tweeter and waveguide rather than the compression driver found in the larger MX-30 series.
LCR Frequency Range. 40 Hz – 20 kHz in-room response.
LCR Drivers. Each main speaker uses a single 255 mm (10-inch) paper cone mid-bass driver and a 26 mm (1-inch) doped fabric dome tweeter coupled to a 90° x 40° short-throw waveguide.
LCR Power & Sensitivity. Handles 100 – 500 watts RMS at 8 ohms with a high sensitivity of 97 dB.
Subwoofer Frequency Range. 25 Hz – 200 Hz in-room response, requiring a 25 Hz high-pass filter.
Subwoofer Drivers. Each subwoofer houses a single 380 mm (15-inch) paper cone driver with a 100 mm (4-inch) voice coil in a front-vented bass reflex enclosure.
Krix MX-20 delivers a true commercial cinema grade sound signature—characterized by effortless dynamic range, pinpoint dialogue clarity, and massive headroom without distortion. Because Krix equips the majority of commercial movie theaters in Australia, their Series MX line brings that exact "wall of sound" directly into residential rooms.
With high sensitivity ratings (97 to 98 dB), both systems easily hit commercial Dolby reference levels,105 dB peaks for mains, 115 dB for LFE using modest amplifier power. Action scenes jump from quiet whispers to sudden explosions without sounding strained or compressed. LFE stands for Low-Frequency Effects. It is the dedicated deep-bass audio track in a surround sound mix.
The front baffles are wrapped in thick acoustic foam, sound bouncing off the back of the projection screen is absorbed rather than reflected, this eliminates muddiness and keeps vocal intelligibility razor-sharp.
The 90° x 40° horn and waveguide designs focus sound directly onto the seating area and away from side walls and ceilings, improving imaging and minimizing early room reflections.
Krix MX-20 (Original). Reviewers describe the original MX-20 as smooth, well-balanced, and cohesive. Its 1-inch doped fabric dome tweeter offers a slightly softer, more forgiving top end compared to compression drivers, paired with punchy mid-bass from the 10-inch woofers. Its dual 15-inch subwoofers deliver tight, tactile bass down to around 25–30 Hz.
Krix MX-20 Mk2. Switching to a 12-inch woofer and a compression driver brings the Mk2 much closer to the MX-30's sonic character. It sounds noticeably more authoritative, crisp, and dynamic at high volumes than the original Mk1.
The MX-30i sounds larger, faster, and more visceral. Its 15-inch LCR mid-bass drivers produce massive chest-thumping mid-bass slam, while the compression driver projects crisp high-frequency detail across larger rooms (up to 14 meters long). Upgrading to dual 18-inch infrasonic subwoofers allows the MX-30i to dig well below 20 Hz, producing deep, pressurizing bass you physically feel in your seat.
For most setups, we would recommend the Krix MX-20 to go with the Krix Cyclonix 15 rather than 18-inch subwoofers. The 15-inch drivers provide a tighter acoustic match with the MX-20 main speakers, fit smaller baffle walls, and already deliver massive output for medium-sized rooms. We recommend up to 18-inch subwoofers like the Cyclonix 18 if you have a large room, multiple rows of seating, or want deep infrasonic bass below 20 Hz.
Pairing a Krix MX-20 front stage with two Cyclonix 15 subwoofers driven by the Krix KA-1000X4 amplifier delivers a tight, high-impact, and seamlessly cohesive commercial cinema sound. Because the Cyclonix 15 uses the exact same 15-inch driver, voice coil, and tuning as the MX-20's stock subwoofer modules, all four subwoofers (the two in the MX-20 plus the two Cyclonix 15s) share identical acoustic speed and tonal character.
Running four identical 15-inch drivers, two in the MX-20 baffle wall and two Cyclonix 15s (typically placed at the rear of the room) gives you massive air-moving capability in the 25 Hz to 120 Hz punch zone. Bass hits feel fast, tight, and visceral without overhang or muddiness.
Placing the two Cyclonix 15s at the back or sides of the room to balance the two front MX-20 subs cancels out room standing waves. Every seat, even across multiple rows gets even, consistent bass response without booming corners or dead zones.
The KA-1000X4 comes pre-loaded with Krix-engineered DSP presets tailored specifically for the MX-20 subs and Cyclonix 15. It automatically applies the required 25 Hz high-pass filter and 1,000W driver protection limiter. This keeps the bass clean and distortion-free even at commercial Dolby reference volume (115 dB LFE peaks).
The Cyclonix 15's 15-inch drivers use high-velocity treated paper cones matching the MX-20 LCR speakers, bass transitions smoothly from the screen channels to the subwoofers. With the Cyclonix 15, you get massive headroom, clean mid-bass slam, and balanced room coverage without the risk of larger 18-inch subwoofers overpowering the MX-20 main speakers. Four subwoofers can be powered cleanly off a single 4-channel KA-1000X4 amplifier (one channel per 8-ohm sub).
There is a trade off. Unlike the 18-inch Cyclonix 18 or MX-30i subwoofers, the 15-inch drivers roll off naturally below 25 Hz. You get chest-thumping impact and room-filling weight, though slightly less of the sub-20 Hz infrasonic rumble found in 18-inch setups.
In a 9.4.6 reference-grade system, we highly recommend the following cinema configuration for massive, effortless commercial-grade sound with pinpoint spatial accuracy. By combining Australian commercial cinema acoustics from Krix with high-current Canadian amplification from Anthem, the setup transforms a dedicated room into a cohesive, tactile sound bubble.
For newcomers to dedicated home theater, the most striking feature here is the Krix MX-20 modular front wall. Instead of placing bulky speakers beside or below a television, these slimline modules hide behind an acoustically transparent projection screen.
Seamless Dialogue and Action. Voices and on-screen effects emanate directly from the actors’ mouths and moving objects rather than from the edges of the room.
Effortless Dynamics. With 97 dB sensitivity and 10-inch mid-bass drivers paired with horn-loaded waveguides, the front three channels handle sudden shifts from a faint whisper to a deafening explosion without straining or sounding harsh.
A 9.4.6 layout places nine speakers at ear level, four subwoofers around the room, and six speakers overhead. This geometry eliminates “dead zones” where sound gets lost between speakers.
Precision Aiming on the Walls. Six Krix Hyperphonix 45 speakers handle the wide, side, and rear surround duties. Their angled baffles and 90° x 90° waveguides fire audio directly toward the seating area rather than bouncing it wildly off nearby walls, keeping directional cues sharp.
Seamless Overhead Atmosphere. Six Krix IC-52 in-ceiling speakers use angled baffles to aim overhead effects—like rain, helicopters, or echoing footsteps—straight down to the listeners. Because they share Krix’s sonic voicing, sound pans smoothly from the screen, past your ears, and across the ceiling.
4 Subwoofers
The “.4” in this system combines the two 15-inch passive subwoofers built into the MX-20 front wall with two standalone Krix Cyclonix 15 units.
Driven by a dedicated Krix KA1000X4 DSP amplifier, these four 15-inch drivers move massive amounts of air. You do not just hear low-end frequencies, you feel them in your chest and seat and we kid you not.
Running four subwoofers across the room cancels out standing waves, ensuring that every seat gets tight, punchy bass rather than one boomy corner and one weak spot.
Speakers are only as good as the electronics controlling and powering them, and this rack provides massive headroom.
Introducing the "Brain". The Anthem AVM 90 acts as the central nervous system. Its proprietary ARC Genesis room correction listens to your specific room’s acoustics and digitally tunes all 15 speakers and four subwoofers so they blend seamlessly.
Introducing the "Muscles". Three units of Anthem MCA 525 Gen 2 amplifiers provide 15 discrete channels of clean Class-AB power at 225 watts per channel into 8 ohms. This massive reserve power keeps background noise virtually silent while giving the speakers instant grip and control during complex, loud movie climaxes.
Watching A Quiet Place on this 9.4.6 Krix and Anthem system transforms the movie from a thriller you watch into an environment you physically inhabit. The film’s Dolby Atmos sound design is built on extreme dynamic contrast—stretching near-total silence to its breaking point before erupting into violent, percussive chaos—and every component in this specific signal chain is engineered to expose that contrast without compromise. Most home theaters fail A Quiet Place during its quietest moments because amplifier noise or room reflections blur faint audio cues.
Pitch-Black Noise Floor. Driven by three Anthem MCA 525 Gen 2 Class-AB amplifiers and processed by the Anthem AVM 90, the signal path exhibits virtually zero audible hiss or hum. When the film cuts to complete silence—such as the opening supermarket sequence or scenes told from Regan’s deaf perspective—the room feels vacuum-sealed.
Micro-Detail Retrieval. Because the Krix MX-20 front stage boasts a high 97 dB sensitivity with commercial horn-loaded waveguides, it requires only fractions of a watt to reproduce ultra-low-level detail. You hear the microscopic grit of bare feet pressing into sand trails, the dry rustle of hands signing in the air, and the strained intake of breath before a character steps onto a creaking floorboard.
Screen-Anchored Realism. With the MX-20 concealed behind an acoustically transparent screen, tiny foley sounds—like a wooden Monopoly piece tipping over or a lantern handle shifting—originate from the exact visual coordinates on screen rather than from boxes flanking the image.
The combination of nine ear-level channels, four 15-inch subwoofers, and six overhead channels allows the room to shift size and atmosphere from scene to scene.
The Opening Bridge Sequence: As the family walks silently down the gravel road, ambient wind and distant forest sounds wrap subtly around the six Krix Hyperphonix 45 surround speakers. When the toy space shuttle suddenly activates, its high-pitched electronic chime slices through the dead silence from the rear-right surround space with startling clarity, followed immediately by heavy, low-frequency footsteps tearing through the trees across the room.
The Farmhouse and Overhead Dread: When Evelyn is trapped inside while a creature stalks the upper floor, the six Krix IC-52 in-ceiling speakers become the star of the show. Because their drivers are physically angled toward the seating area, the heavy, scraping claws and shifting weight of the monster feel genuinely localized inside the ceiling structure directly above your head. As the creature moves from the hallway toward the stairwell, the sound pans smoothly from the top-front channels to the top-rear channels without any gap.
The Cornfield Chase: Surrounded by tall stalks at night, the 9.4.6 bubble closes in around the listener. Whispered breathing sits intimately in the front stage while rustling corn stalks, distant clicking echolocation, and heavy footsteps dart unpredictably between the front-wide, side-surround, and rear-surround Hyperphonix 45 speakers. Their controlled 90° x 90° horn dispersion keeps reflections off the walls, ensuring you hear sharp, pinpoint directional cues rather than a muddy wash of noise.
The Grain Silo: When the children fall into the grain silo, the acoustics shift instantly to a tight, metallic, claustrophobic chamber. The Anthem AVM 90’s ARC Genesis room correction keeps midrange resonances clean, allowing you to hear the rushing cascade of corn kernels swirling around all sides of the room while the heavy metal hatch slams shut overhead with a resonant, pressurized thud.
The Flooded Basement: As water rushes down the stairs and a creature hunts in the dark, the system balances delicate water lapping in the surrounds with sudden, violent impacts. When the monster smashes through wooden shelving or lands in the water, the sound hits with instantaneous speed and zero harshness.
The defining hallmark of commercial cinema speakers like Krix is headroom, the ability to go from a whisper to deafening volume in a fraction of a millisecond without compressing or distorting.
Zero Compression on Jumpscares: Conventional home hi-fi dome tweeters often harden or compress when hit with sudden, loud transients. The horn-loaded compression drivers in the MX-20 deliver screaming monster vocalizations, shattering glass, and shotgun blasts at full cinema reference levels with effortless clarity, triggering a genuine physical startle response every time.
Tactile Low-Frequency Terror: Powered by the dedicated Krix KA1000X4 DSP amplifier, the four 15-inch subwoofers—two integrated into the MX-20 front wall and two standalone Krix Cyclonix 15 units—pressurize the entire room effortlessly. Every heavy footstep of the creatures sends a tight, subterranean thud straight through the floor and into your chest. Because four subwoofers even out room modes across the seating area, there is no sluggish bass overhang each impact hits like a sharp physical blow and stops on a dime, returning the room immediately to suffocating silence.
In a 9.4.6 Krix and Anthem ecosystem, the MX-20 does more than upgrade your audio, it erases the boundary between your room and the world on screen, pulling you straight into the heart of every frame.

Krix Megaphonix In-Wall
While the massive Theatrix mains are 3-way, horn-loaded beasts designed to dominate massive rooms, pairing the Krix Megaphonix In-Wall with the Krix UCX-118 infrasonic subwoofer creates a highly detailed, punchy, and theater-accurate soundstage. The Krix Megaphonix In-Wall is a high-efficiency 2-way home cinema speaker that uses a 10-inch mid-bass driver coupled to a proprietary waveguide fabric dome tweeter.
When you pair them with the award-winning, 18-inch UCX-118, the resulting presentation shifts in a very distinct, compelling way. Unlike traditional commercial cinema speakers that use aggressive compression drivers, the Megaphonix features a specialized doped fabric dome tweeter sitting inside a short-throw waveguide. This gives the top end smooth, natural, and pristine clarity. High-frequency details, like rain, shattering glass, or delicate acoustic instruments, sound smooth and airy rather than sharp or piercing, sitting beautifully on top of the deep bass foundation.
The Megaphonix's 10-inch paper cone driver is exceptionally fast and efficient (95 dB sensitivity), delivering a tight, chest-thumping punch in the mid-bass registers. Because the Krix UCX-118 also utilizes high-velocity treated paper cone technology, their driver speeds and tonal characteristics match perfectly. The transition from the 10-inch driver down to the subterranean 10 Hz of the 18-inch subwoofer is flawlessly cohesive. The Krix Megaphonix In-Wall family features incredibly shallow profiles—especially the Megaphonix Flat and In-Wall variants at just 150–162 mm deep. Pairing them with the slim 321 mm profile of the UCX-118 allows you to build a system that sounds gargantuan but easily hides entirely behind a false wall or an acoustically transparent projector screen.
Even though the Krix Megaphonix In-Wall is smaller than the Theatrix, it still plays with the authority of a real cinema system. Because the UCX-118 handles the taxing, heavy-lifting low frequencies (10 Hz–200 Hz), it completely unburdens the Megaphonix mains. This allows the 10-inch drivers to focus entirely on pristine dialogue and midband effects with incredibly low harmonic distortion.
Deploying the Krix Megaphonix for all three front channels (LCR) and the rear surrounds, anchored by dual Krix UCX-118 subwoofers, creates a perfectly uniform, high-output surround sound environment with a terrifyingly deep low-frequency foundation.
You will experience a flawless 360-degree acoustic match. Because the exact same speaker model handles the front stage and the rear effects, your room achieves absolute tonal consistency. When a spaceship flies overhead or a car speeds past from the front screen to the back of the room, there is zero change in the audio's tone, weight, or clarity.
You will experience a smooth, deep, and immersive home cinema atmosphere. The waveguide-loaded fabric dome tweeters in the Megaphonix create an incredibly wide, seamless dome of sound. Surround effects feel airy and atmospheric, wrapping around you completely rather than sounding harsh or drawing your attention directly to the physical speaker boxes.
You will experience pressurized, room-filling infrasound. Stepping up to dual UCX-118 subwoofers completely transforms the room's energy. With two massive 18-inch drivers moving air together, you don't just hear the bass—the room undergoes a physical pressure change. Subterranean frequencies down to 10 Hz hit you with a visceral, tactile chest impact. Running dual subwoofers drastically improves bass response across all seating positions. It actively smooths out acoustic room modes, eliminating annoying "boominess" in the corners and preventing dead spots where bass disappears, resulting in a tight, uniform punch.
Because the dual UCX-118s handle the punishing low-end lifting, the entire Megaphonix array is completely unburdened. The 10-inch mid-bass drivers focus entirely on pristine midrange and lightning-fast vocal dynamics, allowing the entire system to hit reference theater volume levels with zero distortion or strain.

Krix Phonix In-Wall
The Phonix In-Wall sits inside Krix's Dedicated Home Cinema lineup, engineered specifically to match commercial-style cinema speakers (such as the Euphonix, Vortex, or Series MX systems) in dedicated theater rooms. At 7kg each with a 120mm deep enclosure and a heavy-duty 6.5-inch woofer, the Phonix In-Wall is built for higher dynamic headroom and deeper bass extension (45Hz) in larger, purpose-built rooms.
Key Features
Application: Built for side surround, rear surround, or overhead/ceiling effect roles in a home cinema.
Low-Frequency Extension: Delivers bass response down to 45Hz from a compact in-wall footprint.
Bass Driver: Features a 165mm (6.5") driver with a paper cone, a 33mm voice coil on an aluminum former, a ventilated spider, and an aluminum flux stabilisation ring to reduce distortion.
Tweeter: Uses a 26mm (1") ferrofluid-cooled, doped fabric dome tweeter with a large roll surround.
Build & Enclosure: Front-vented bass reflex cabinet design with gold-plated binding post terminals.
Specifications
Frequency Range: 45Hz – 20kHz (-10dB)
Power Handling: 50 – 150 Watts RMS recommended amplifier power
Sensitivity: 88dB (2.83V / 1m)
Impedance: 8 Ohms
Crossover Point: 1.8kHz
Dimensions: 388mm high × 260mm wide × 120mm deep cabinet (Recommended cut-out: 393mm high × 265mm wide)
Weight: 7kg each
The Krix Phonix In-Wall delivers a smooth, dynamic, and non-fatiguing cinema sound with punchy bass weight, while the Krix IW-50 produces a more focused, articulate, and balanced sound tailored for dialogue clarity and stereo music.
Because Krix voices its speakers around commercial cinema standards, both share a clean, low-distortion house signature, though their different driver layouts shape how they sound in a room.
Krix Phonix In-Wall Sound Profile
Full-Bodied Low End. Its larger 6.5-inch paper-cone woofer and deeper cabinet allow it to dig down to 45Hz. Action effects, panning helicopters, and ambient room swells carry noticeably more physical weight and warmth.
Smooth, Non-Fatiguing Highs. The 26mm doped fabric dome tweeter is damped to keep top-end frequencies controlled rather than bright or piercing. Even during loud action sequences, surround effects blend seamlessly without drawing attention to the speaker's physical location in the wall.
Wide, enveloping dispersion designed specifically for side, rear, and overhead surround duties, it projects a broad sound field that wraps around the seating area rather than beaming directly at one spot.
Pairing Krix Phonix In-Wall surrounds, Krix IC-52 overhead speakers, and three Krix Cyclonix 18 passive subwoofers forms a reference-grade, commercial-cinema inspired 9.3.4 home theater layout. Each component matches Krix's signature dynamic, low-distortion voicing while handling a distinct spatial role.
Using the Krix Phonix In-Wall for your main front, rear surrounds, side surrounds, and wides gives your 9-channel base layer consistent 6.5-inch driver authority and smooth off-axis dispersion. Because they handle frequencies down to 45Hz cleanly, panning effects across the room carry real weight.
Overhead Atmos Layer (IC-52). The Krix IC-52 features a 20-degree angled baffle inside a sealed, front-vented backbox. Aiming the four ceiling channels toward the main listening position keeps overhead effects crisp and well-localized, while its 90dB sensitivity easily keeps pace with high-output cinema speakers.
Triple Subwoofer Array (3 × Cyclonix 18). Each Krix Cyclonix 18 houses a high-efficiency (96dB sensitivity) 18-inch driver in a slim 270mm-deep cabinet. Running three units across the room such as two in the front baffle wall and one at the rear evens out room modes so every seat experiences tight, tactile bass impact.
The Cyclonix 18 is a passive subwoofer requiring external power amplification 1000W to 1,400W RMS per unit at 8 Ohms. Krix recommends applying a 20Hz high-pass filter and a 1,000W limiter via DSP, such as a Krix KA-1000X4
Processing & Amplifier Channels. A 9.3.4 configuration requires 13 processed speaker channels plus independent subwoofer outputs, ideally 3 discrete sub outs on a processor like a Trinnov, StormAudio, Anthem AVM 90, or Marantz AV 10 for individual time alignment and room correction.
A 9.3.4 system built around Krix speakers, Anthem processing, and dedicated amplification will deliver an extraordinary, commercial-cinema-level experience for A Quiet Place, a movie renowned for its extreme dynamic range and reliance on subtle atmospheric cues punctuated by sudden, violent bursts of sound.
Extreme Dynamic Range & Silence (Anthem AVM 90 & MCA 525)
Pin-Drop Clarity: A Quiet Place spends long stretches in near-total silence where tiny sounds—a creaking floorboard, rustling leaves, or shallow breathing—carry massive tension. The Anthem AVM 90 features audiophile-grade DACs with a vanishingly low noise floor, ensuring these delicate details emerge from a completely black background without hiss or distortion.
Effortless Headroom: When the silence is shattered by a dropped lantern or a monster attack, the three Anthem MCA 525 power amplifiers provide massive current and headroom. The transition from whisper-quiet to reference-level volume will be instantaneous and completely uncompressed.
Three-Dimensional Tension (Phonix In-Wall & IC52)
Using Krix Phonix in-wall speakers across your 9 ear-level channels creates an airtight, timbre-matched soundstage. As the creatures skitter around the perimeter of the farmhouse or through the cornfields, the sound will pan smoothly around the room without any tonal shifts.
The four Krix IC52 ceiling speakers are voice-matched to the Phonix line. In scenes where the characters are hiding in the basement while creatures prowl on the floorboards directly above them, the Atmos height channels will place those heavy footsteps unmistakably over your head, heightening the claustrophobia.
Visceral, Tactile Impact (3x Cyclonix 18 & KA1000x4)
Chest-Thumping LFE: The creatures' footsteps, low-frequency growls, and the film's ominous sub-bass drones rely heavily on deep, authoritative low-end. Driving three Cyclonix 18 subwoofers with the Krix KA1000x4, which provides dedicated DSP and 1000W per channel outputs massive air-moving capability. You will physically feel the sub-bass pressure in your chest before you even hear the threat on screen.
Three 18-inch subwoofers, calibrated via the AVM 90's ARC Genesis room correction, which manages up to four independent subwoofer outputs, will smooth out room modes. Every seat in the theater will experience clean, tight, fast, and devastatingly punchy bass rather than boomy or uneven low end.
Immersive Experience
With proper calibration using ARC Genesis, this system will not just play A Quiet Place it will physically put you inside the movie. The contrast between the dead-silent acoustic space and the terrifying, room-shaking low-end impacts will make it an intense, reference-grade showcase for your theater.
Krix Megaphonix In-Wall
The Krix IW-50 is a high-performance, 2-way in-wall LCR (Left, Center, Right) and surround loudspeaker manufactured in Adelaide, Australia
Key Features & Design
Configuration: 2-way configuration, it places the tweeter between two bass drivers for smooth, continuous sound dispersion and a balanced tonal structure.
Drivers:
Dual 100 mm (4-inch) doped paper cone low-frequency drivers with 25 mm high-temperature Kapton voice coils.
26 mm (1-inch) dual concentric diaphragm ring radiator tweeter featuring a waveguide centre plug for controlled high-frequency directivity.
Enclosure: Unlike many, Krix IW-50 is built with a fully enclosed rear backbox (bass reflex, front-vented) that ensures consistent bass performance regardless of the wall cavity's shape or size, while also minimizing sound leakage into adjacent rooms.
Engineered to fit into standard 70 mm wall studs (allowing 10 mm for standard drywall depth). It features a trimless, paintable, rust-resistant stainless steel magnetic grille that blends flush with the wall.
Can be used as left, center, and right (LCR) front speakers, side or rear surrounds, or in stereo pairs. While the Krix IW-50 works well as an LCR option in medium-sized multi-purpose rooms, it won't offer quite the same massive physical impact as Krix's larger, higher-end in-wall lines.
Technical Specifications
Frequency Range: 55 Hz – 40 kHz (in-room response)
Power Handling: 20 – 140 Watts RMS recommended amplifier power
Sensitivity: 89 dB (2.83 volts at 1 meter)
Impedance: Nominally 6 Ohms (minimum 3.5 Ohms)
Cut-out Dimensions: 555 mm x 170 mm
Physical Dimensions: 596 mm high x 211 mm wide x 79 mm mounting depth
Weight: 4 kg each
The Krix IW-50 delivers a balanced, dynamic, and cinema-focused sound characterized by clear midrange vocals, smooth high frequencies, and consistent dispersion. While it excels at high-volume movie playback without harshness, real-world owners emphasize that pairing it with a subwoofer is essential for satisfying low-end impact and musical fullness.
Krix carries over technology from its commercial cinema speakers to give the IW-50 a dynamic, engaging presentation. Some owners even said it has a touch of commercial theater horn-like sound, which is their classic signature.
Smooth Highs and Loud Output. The 26 mm ring radiator tweeter features a softer top end that allows you to push the volume to high reference levels without ear fatigue.
Because the speaker uses a 2-way D'Appolito layout and a sealed rear backbox, its tonal balance and bass response remain predictable regardless of the wall cavity behind it. Retailers like Living Entertainment highlight its natural midrange vocals and clean separation across movie soundtracks.
Although the IW-50 is rated down to 55 Hz, its dual 4-inch drivers cannot produce deep physical bass on their own. Many owners noted that using the IW-50 as front LCR speakers without a subwoofer can result in underwhelming stereo music playback and thinner dialogue clarity.
Pairing the Krix IW-50 with the Krix Cyclonix 15 produces a clean, dynamic, and high-impact sound signature, though the subwoofer significantly outclasses the IW-50 in sheer output headroom. Because both share Krix's signature voicing—using doped paper cone drivers and front-vented bass reflex enclosures—their tonal transition is smooth and cohesive when properly calibrated.
Sonic characteristics of the pairing
The IW-50 rolls off around 55 Hz, while the Cyclonix 15 operates from 25 Hz to 200 Hz. Setting an AV receiver crossover at 80 Hz lets the Cyclonix 15 absorb all heavy low-end duties, freeing the IW-50's dual 4-inch woofers to focus purely on clean midrange vocals and upper-bass punch.
Tonal Consistency. Both speakers rely on paper cone drivers engineered by Krix, giving the mid-bass transition between the in-wall speakers and the subwoofer a natural, unified texture without sounding disconnected.
Effortless Cinema Slam. Designed originally as a supporting subwoofer for Krix's commercial-style Series MX theater systems, the Cyclonix 15 delivers fast, tactile chest-thumping bass. Action sequences and low-frequency effects (LFE) gain massive scale that compact in-wall speakers cannot produce on their own.
Ideal for small to medium small space
The Cyclonix 15 is built for extreme cinema volume, boasting a 96 dB sensitivity rating and handling up to 1,400 Watts RMS. By comparison, the IW-50 has an 89 dB sensitivity and handles up to 140 Watts RMS. In a large room at reference volume, the IW-50 will reach its dynamic limits long before the Cyclonix 15 breaks a sweat.
Unlike standard powered home theater subs, the Cyclonix 15 is a passive subwoofer with no built-in amplifier. You must pair it with a dedicated external power amplifier (ideally delivering 800W to 1,000W at 8 Ohms) and apply a 25 Hz high-pass filter with a 1,000W limiter as recommended by Krix.
The Cyclonix 15 is a front-vented cinema sub tuned for maximum mid-bass output, it rolls off sharply below 25 Hz. Placing it near a wall-floor boundary or room corner helps reinforce its deepest sub-bass response.
In a small-to-medium living room or media space, this pairing sounds balanced, articulate, and remarkably punchy while keeping a slim physical footprint (the Cyclonix 15 is only 270 mm deep). If you are building a large dedicated theater and plan to push the Cyclonix 15 hard, stepping up your front LCR speakers to larger Krix models, such as the Megaphonix or Phonix series will better match the subwoofer's massive dynamic headroom.
Building a 9.3.4 Dolby Atmos system using the Krix IW-50, Krix IC-52, triple Cyclonix 15 subwoofers, and the KA-1000X4 creates a cohesive, theater-grade speaker package. Because every speaker in this lineup shares Krix's signature doped paper cone drivers and 26 mm ring radiator tweeters, objects pan seamlessly around and above the room with identical timbre.
How the Krix IC-52 fits your 9.3.4 layout
Angled Acoustic Dispersion. The Krix IC-52 features a 20-degree angled baffle that aims sound directly toward your primary seating area rather than straight at the floor. This reduces ceiling reflections and sharpens overhead Atmos effects.
Tonal Match with IW-50. Equipped with a 130 mm (5") doped paper cone woofer and the same 26 mm ring radiator tweeter found in the IW-50, the IC-52 blends seamlessly with your ear-level speakers.
Like the IW-50, the IC-52 houses a fully enclosed rear backbox. This prevents sound from leaking into the roof cavity or upper floors and ensures consistent bass down to 45 Hz.
Each IC-52 requires a 247 mm cut-out diameter and 193 mm of ceiling mounting depth, which is deeper than the 79 mm wall depth of the IW-50.
A 9.3.4 configuration requires 13 speaker amplification channels plus 3 high-power subwoofer channels (16 channels total).
Subwoofer amplification with a single KA-1000X4 provides 4 high-output channels (1,000W at 4 Ohms per channel, or 2,700W bridged). It can power all three Cyclonix 15 subwoofers off three individual channels using Krix's built-in DSP presets and 25 Hz high-pass protection, leaving the fourth channel as a spare or for a fourth sub later.
Pairing the Anthem AVM 90 and MCA 525 Gen 2 with the 9.3.4 Krix system is a reference-grade electronics match that extracts the maximum dynamic range, clarity, and bass control from your speakers. Why This Electronics Pairing Excels
The Anthem AVM 90 features four independent subwoofer outputs alongside Anthem Room Correction (ARC Genesis). Instead of daisy-chaining your three Cyclonix 15 subwoofers, ARC Genesis individually measures, time-aligns, and EQ-balances all three subs to eliminate bass nulls across your seating rows.
Effortless Clean Power (MCA 525): The MCA 525 delivers 225 Watts per channel into 8 Ohms and 400 Watts per channel into 4 Ohms with ultra-low distortion. Because your IW-50 (6 Ohms, 140W max) and IC-52 (6 Ohms, 120W max) dip down to 3.5–4 Ohms at certain frequencies, the MCA 525's massive toroidal power supply keeps transient peaks effortless without compression.
Balanced XLR Signal Chain: Both the AVM 90 and MCA 525 (as well as the Krix KA-1000X4) support balanced XLR connections, ensuring a dead-silent noise floor even over longer rack-to-amp cable runs.

Krix Cyclonix 18
The Krix Cyclonix 18 is a high-output, passive subwoofer designed specifically for dedicated home cinema and custom installation. It is built to deliver the high sound pressure levels and low distortion associated with commercial cinema, rather than the compact, integrated form factor typical of many consumer subwoofers.
The Cyclonix 18 is a large, furniture-grade box that is often installed behind an acoustically transparent screen or built into a baffle wall.
Passive Design: It does not have a built-in amplifier. You must pair it with a separate power amplifier, which Krix recommends for better thermal management and flexibility in choosing amplification.
Driver: It features a massive 455mm (18-inch) paper cone driver with a 100mm (4-inch) edge-wound voice coil and a dual spider assembly. This is designed for high excursion and power handling.
Cabinet: The enclosure is made of heavily braced MDF and uses Krix's proprietary "X" brace system to eliminate panel resonances. It uses a front-vented bass reflex design, which makes it easier to place near walls or behind screens.
Efficiency and "Effortlessness": With a sensitivity of 100 dB (2.83V/1m), this subwoofer needs very little amplifier power to reach high volume levels . A reviewer noted that because it is so efficient, it sounds "relaxed and natural" even at very high output, whereas less efficient subs can start to sound strained or compressed.
Speed and Impact: The bass is consistently described as "fast" and "forceful." Because the driver is large and the cabinet is tuned for high output, it excels at delivering the sharp, punchy transients of gunshots and explosions without sounding boomy or slow.
High-Output Capability: One retailer claims a single unit can produce peaks of 124dB in a typical room . While this is a retailer's figure and not an official Krix spec, it illustrates the design goal: providing "reference level" output for large, dedicated rooms.
