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.
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.

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 aluminium/paper cone, an oversized motor system with a vented design for the voice coil, ensuring vanishingly low distortion and exceptional precision.

Turn up the power

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.

Designed to perform

The compact, sealed box construction improves flexibility of positioning as well as the speed and clarity of the performance.

Attention to detail

The low-profile heatsink ensures that the high-performance electronics are kept in optimum conditions.

Finished to perfection

With a minimal and timeless design, the KC92 is easy to match with any speakers and work beautifully with any interior.

Effortless wireless integration

The KW1 enables optimal placement of the KC92 without being limited by cables. High-quality wireless transmission ensures the delivery of every nuance and impact from your favourite movies and music.

Stack up for next level bass

The KSK92 subwoofer stacking kit allows you to effortlessly merge up to three KC92 subwoofers into a single, powerful unit, and deliver even higher levels of output and performance without sacrificing valuable floor space.
