Short answer: the SVS SB-2000 for amplifier headroom, the Kef KC62 for compact size. The SB-2000 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 $1699.99 against the SB-2000’s $899.
On the Kef KC62 side: Dual 6.5-inch force-canceling drivers with 1000W in ultra-compact basketball-sized sealed enclosure.
The case for the SVS SB-2000: Sealed 12” with 550W RMS, 1500W peak Sledge amplifier.
Buy the SVS SB-2000. It is rated higher for sound quality than the Kef KC62 and costs less, so there is no real case for the other one.
