Short answer: the SVS SB-2000 Pro for amplifier headroom, the Kef KC62 for compact size. The SB-2000 Pro is a sealed 12-inch sub driven by a 550W RMS, 1500W peak Sledge amplifier. The KC62 fits an ultra-compact basketball-sized sealed enclosure with dual 6.5-inch force-canceling drivers and 1000W, though it costs $1,699.99 against the SB-2000 Pro’s $899.
Buy the SVS SB-2000 Pro. It is rated higher for sound quality than the Kef KC62 and costs less, which makes it the one to get unless you need something the other one does better.

SVS SB-2000 Pro: $899.00 each Amazon eBay
Older models: the SVS SB-2000 (ranked higher, rated 3.9/5) and the SVS SB12-Plus (ranked lower, rated 3.6/5).
Pros: A compact sealed 12-inch subwoofer, about 37cm on each side, with a 550W RMS (1,500W peak) Sledge amplifier and SVS’s smartphone app for volume, crossover, phase, room gain compensation and parametric EQ from the listening seat. Erin’s Audio Corner measured a 114.7dB CEA-2010-A average from 40 to 80Hz, and SVS rates it at 19-240Hz within 3dB.
Cons: Output is modest next to larger or ported subwoofers: Erin’s Audio Corner measured about 102.5dB at 20Hz, and he judged the SB-3000, about $200 more, the better value for its considerably higher output. Sealed designs this size run out of headroom sooner in large rooms.
