Short answer: the Monoprice SW-12. It ranks #32 of 137 subwoofers at $230; the Kef KC62 ranks #137 and costs $1519.99, so there is not much of a tradeoff to weigh.
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 Monoprice SW-12: 12-inch ported with 400W RMS (600W peak) on a budget at just $230. Hits hard with clean tight transient response. The catch: Entry-level build quality, ported enclosure room interaction, and lower 112.3 dB output capability.
Buy the Kef KC62 if the price matters more than the ranking. Buy the Monoprice SW-12 if the ranking matters more than the price.
