Short answer: the SVS SB-3000 for measured output, the Monoprice SW-12 for the $932.63 gap. The sealed 13-inch SVS is rated 800W RMS (2500W peak) with a 118.7dB average and exceptional accuracy. The Monoprice is a 12-inch ported sub at 400W RMS (600W peak) with 112.3 dB output capability, and the lower price is its main argument.
On the SVS SB-3000 side: 13-inch sealed with 800W RMS (2500W peak) delivers 118.7dB average with exceptional accuracy. The tradeoff: Ported cabinet room-mode dependency, compact 25 kg (55.1 lbs) size limits bass extension, and a $1,199 investment.
Buy the Monoprice SW-12. It is rated higher for sound quality than the SVS SB-3000 and costs less, which makes it the one to get unless you need something the other one does better.
