Same look, better performance

Evolved from the KF92, the KC92 features the same elegant, compact and robust design, but optimised performance.

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 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.

Multiple power modes

'Auto wake up' detects audio signals for instant readiness, 'Always on' mode keeps it ready to play instantly, and '12V trigger' provides automatic wake-up.
