Short answer: the SVS SB-2000 for amplifier power, the Monoprice SW-15 for cabinet size and room gain. The sealed SVS is a 12-inch design with 550W RMS and a 1500W peak Sledge amplifier. The Monoprice is 15-inch ported with 600W RMS (800W peak) and a Large-room Bassaholic rating, though budget-tier build and limited dynamic headroom are the tradeoff.
What the Monoprice SW-15 gets right: 15-inch ported with 600W RMS (800W peak) delivers Large-room Bassaholic rating. The tradeoff: Budget-tier design, ported room gain dependency, 30 kg (66.1 lbs) mid-size, and limited dynamic headroom.
On the SVS SB-2000 side: Sealed 12” with 550W RMS, 1500W peak Sledge amplifier.
Buy the Monoprice SW-15. It is rated higher for sound quality than the SVS SB-2000 and costs less, which settles it without a real tradeoff to make.
