Short answer: the KEF KC92. It ranks #203 of 212 subwoofers by sound quality, rated 3.0/5, at $2,449.95. The KEF KC62 ranks #212, rated 2.5/5, at $1,589.95, $860 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for the KEF KC62: Dual 6.5-inch force-canceling drivers with 1000W in ultra-compact basketball-sized sealed enclosure. Watch for: A hard limiter caps low bass as you turn it up: at 85 to 90dB it plays about 74dB at 20Hz, 6dB below the KEF KF92, and 10Hz output is about 15dB lower.
The KEF KC92 is the better-sounding pick. 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. Watch for: No independent measurements yet, so its output can’t be compared with ranked subwoofers.
Buy the KEF KC92. It is rated higher for sound quality, and the $860 you would save on the KEF KC62 does not close the gap.
Worth knowing: the KEF KC92 has not been measured yet. Its rating is estimated from related models, with a likely range of 2.8 to 3.2, so treat this verdict as provisional.
