TELL ME MORE ABOUT THE

Krix UCX-118 Subwoofer

The Krix UCX-118 is a high-performance cinema subwoofer engineered to deliver exceptionally deep bass, powerful low-frequency impact, and an immersive home cinema experience. Designed for serious movie enthusiasts and dedicated home theatre installations, it reproduces the lowest cinematic frequencies with authority, allowing you to experience everything from explosive action sequences to subtle atmospheric effects with greater physical impact. Its impressive frequency range extends down to 10 Hz with DSP, bringing infrasonic effects to life so that bass is not just something you hear, but something you can feel.

At its core, the UCX-118 features a massive 18-inch high-excursion driver with a treated paper cone, a 4-inch voice coil, and a neodymium magnet, engineered to deliver substantial bass output with low distortion. Despite its powerful performance capabilities, its carefully designed enclosure maintains a relatively compact footprint for a subwoofer of this class. With support for external amplification and DSP, including Krix-optimised settings, the UCX-118 offers flexible integration into high-end home cinema systems. Whether installed as a single subwoofer or combined with multiple units for more consistent bass throughout a room, it delivers the depth, control, and tactile immersion needed to transform movie nights into a truly cinematic experience.

Deep Infrasonic Bass Down to 10 Hz

The UCX-118 reaches frequencies as low as 10 Hz when used with DSP, reproducing the powerful low-frequency effects that bring cinematic soundtracks to life. This exceptional bass extension helps create a more realistic sense of scale and physical impact during explosions, rumbling effects, and dramatic movie scenes. It is an excellent choice for home cinema enthusiasts who want to experience the deepest bass their system can deliver.

Powerful 18-Inch High-Excursion Driver

Equipped with a single 460 mm (18-inch) treated paper cone driver, the UCX-118 is engineered to move substantial amounts of air for impactful low-frequency reproduction. Its 100 mm (4-inch) voice coil, neodymium magnet, and 50 mm peak-to-peak displacement support powerful output while helping maintain control. This advanced driver design makes it well suited to demanding cinema applications where deep, dynamic bass is essential.

High Power Handling for Demanding Cinema Systems

The UCX-118 offers impressive power-handling capabilities of 1,250 watts continuous, 2,500 watts program, and 5,000 watts peak. This capacity makes it suitable for high-output home theatre systems designed to reproduce intense cinematic effects and dynamic soundtracks. External amplification is required, allowing the subwoofer to be paired with a compatible amplifier and DSP configuration suited to the installation.

Compact Enclosure with Impressive Bass Output

Despite its large 18-inch driver, the UCX-118 features an enclosure measuring approximately 665 mm high, 650 mm wide, and 321 mm deep. This design delivers substantial infrasonic performance without requiring the footprint of a much larger cabinet. It is a practical choice for dedicated cinema rooms where powerful bass is needed but installation space must still be managed carefully.

Flexible Single or Multiple Subwoofer Configurations

The UCX-118 can operate as a standalone subwoofer or be deployed in a multi-subwoofer arrangement for improved bass consistency across the listening area. Using multiple units can help reduce room-related bass variations and provide a more even experience for several seating positions. This flexibility makes it suitable for everything from premium private theatres to larger, more demanding home cinema installations.

Correct DSP setup can help manage low-frequency response, crossover behaviour, and system performance according to the installation requirements. Finished in Cinema Black, it also offers a discreet, professional appearance that suits dedicated home theatre environments.
