Short answer: the Monoprice SW-15. It ranks #8 of 137 subwoofers at $374.99; the SVS SB-3000 ranks #9 and costs $1199, so there is not much of a tradeoff to weigh.
What the Monoprice SW-15 gets right: 15-inch ported with 600W RMS (800W peak) delivers Large-room Bassaholic rating. Set against that: Budget-tier design, ported room gain dependency, 30 kg mid-size, and limited dynamic headroom.
On the SVS SB-3000 side: 13-inch sealed with 800W RMS (2500W peak) delivers 118.7dB average with exceptional accuracy. The catch: Ported cabinet room-mode dependency, compact 25 kg size limits bass extension, and $1,100 investment.
Buy the Monoprice SW-15 if the ranking matters more than the price. Buy the SVS SB-3000 if the price matters more than the ranking.
