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.

Made In Adelaide, Australia
The UCX-118 is engineered for flexibility in high-end home theaters. It can be used as a standalone subwoofer or deployed in multi-subwoofer arrays to improve room coverage and consistency. Krix has demonstrated its capabilities in demanding configurations, including an 8-unit setup with Trinnov WaveForming at CEDIA Expo 2026 and a planned 6-unit demonstration for the StereoNET Melbourne Hi-Fi & AV Show.
Designed and manufactured in Adelaide, Australia, the UCX-118 reflects Krix's 50+ years of engineering expertise in cinema sound. Its combination of deep infrasonic extension, high power handling, and a compact, installation-friendly cabinet makes it a compelling choice for those building a reference-level home cinema system.
The UCX-118 was also demonstrated in a 16-channel Storm Audio home cinema system in Kuala Lumpur, Malaysia. This showcase highlighted the subwoofer's ability to integrate seamlessly into a high-channel-count, immersive audio environment within the Southeast Asian market. The KL demonstration further reinforced the UCX-118's suitability for reference-grade theaters where precise bass management and deep infrasonic output are essential.

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.
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.
