• 1000W (2x500W) Class D amplification
• Sealed box construction for a more accurate subwoofer， that is more flexible about placement
• Compact， space saving design with low profile， sculpted heatsink
• Exceptionally versatile controls allowing for easy integration with any loudspeaker and any home environment

Features

• 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
  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.
• Effortless dynamics
  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
  Two 9-inch KEF transducers were conceived specifically for the KF92. They feature a hybrid aluminium/paper cone and an oversized motor system and voice coil. They offer vanishingly low distortion and precision， so every bass moment is uncovered even when they are working at extremes.
• 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
  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.
• More bass， less space
  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.
