The KEF KC92 is not ranked yet. We rank speakers on independent measurements, and none have been published for it so far. It is likely to perform similarly to the model it replaces, though we can’t confirm that until it has been measured. See all Subwoofers rankings for measured picks.

KEF KC92: $2,499.99 KEF eBay
Replaces: the Kef KF92 (ranked #138 of 145 in its size class).
Pros: Twin 9-inch drivers mounted back to back in a force-cancelling layout that reduces cabinet vibration, driven by 1,000W RMS (2 x 500W) of Class D amplification with KEF’s Music Integrity Engine DSP. KEF rates it at 11Hz to 200Hz (±3dB) from a cabinet only about 35cm on each side. Speaker-level inputs and an expansion port for KEF’s KW1 wireless adapter.
Cons: No independent measurements yet, so its output can’t be compared with ranked subwoofers. KEF rates maximum output at 110dB, modest for a subwoofer at this price, so it suits music and smaller rooms more than reference-level home theater.
