Twin 9-inch driver 'force-cancelling' subwoofer

KF92 is a compact, room-friendly subwoofer engineered to deepen every listening experience.

Two massive 9-inch drivers in a force-cancelling configuration are powered by an immense 1000 Watts (RMS) of power. Optimised with KEF's Music Integrity Engine™, KF92 delivers astonishing levels of deep and controlled bass.

Discover the detail in the deep

To reproduce serious bass you need a completely different kind of loudspeaker, one which can cope with huge pressure. KF92 is engineered to blast out huge chunks of lower frequency energy, yet is subtle enough to pick out the delicate details of a double bass. KF92 ensures you don't just feel the air move - you feel the sound move you.

Perfect balance

Effortless dynamics

Two 9-inch drivers are positioned back to back in a force-cancelling design which cancels out the reactive forces which stress conventional subwoofers. This configuration keeps KF92 perfectly balanced so all you'll hear is deep and clean bass at sound pressure levels of upto 110db.

KF92's prodigious drivers are optimised with a clever vented design which reduces viscous drag on the movement of the cone, ensuring they can keep up with even the most demanding impulses.

Bespoke bass

Music Integrity Engine™

KEF's research into digtal sound processing - Music Integrity Engine - is the brains behind KF92. Intelligent Bass Extension optimises the relationship between the amplifier, drivers and cabinet, while placement-dependant EQ allows for seamless integration into any room.

Turn up the power

More bass, less space

KF92’s 1000W (RMS) of Class D amplification (500W RMS per driver) creates immense power., delivering incredible levels of control. This improves timing accuracy and dynamic response, producing a more detailed sound closer to that in the studio.

The compact, sealed box construction improves flexibility of positioning as well as the speed and clarity of performance. The beautiful low profile heatsink ensures that the hard working electronics are kept in an optimum thermal condition.
