Twin 9-Inch Driver Force-Cancelling Subwoofer
Compact yet robust, the KC92 subwoofer features 2 x 9-inch force-cancelling drivers propelled by a formidable 1000W (RMS) of amplification. Optimized with KEF’s Music Integrity Engine®, KC92 subwoofer delivers remarkably deep and impactful bass with exceptional precision, bringing you an immersive, ultra-dynamic listening experience.
Music Integrity Engine® (MIE)
KEF‘s proprietary DSP (Digital Signal Processing) algorithms ensure that every component of the subwoofer works in perfect harmony. Features such as iBX Intelligent Bass Extension provides even deeper and precise bass at any listening level.
Power and Precision in Tandem
The two drivers are positioned in a force-cancelling configuration, neutralising reactive forces and facilitating sound pressure levels of 110dB from a compact, sealed cabinet.
P-Flex Surround
Engineered to better resist the acoustic pressure in the cabinet to allow the driver to move more precisely compared to traditional surround designs.
Distortion-Free Depth
The drivers feature a hybrid aluminum/paper cone, an oversized motor system with a vented design for the voice coil, ensuring vanishingly low distortion and exceptional precision.

The KC92’s twin drivers are powered by 1,000W RMS (2 x 500W), providing exceptional levels of control and the ability to deliver sudden bursts of power precisely when needed.
Well Connected
Versatile connections including KEF SmartConnect and speaker level inputs ensure effortless setup. It also features a line output with High Pass Filter (HPF) for fine-tuned integration.
