Short answer: the SVS SB-3000 for better sound quality, the Monoprice 12in 150-Watt Powered for the lower price. The SVS SB-3000 ranks #15 of 212 subwoofers, rated 4.1/5, at $1,149. The Monoprice 12in 150-Watt Powered ranks #126, rated 3.6/5, at $186.48, $962.52 cheaper.
The SVS SB-3000 is the better-sounding pick. A well made sealed subwoofer with tight, accurate bass and handy app controls, great for music and medium rooms. The catch: Being sealed, it gives up deep-bass output: Audioholics measured 96.6dB at 20Hz and 101.7dB at 25Hz, about 15dB behind the ported SVS PB-3000 from the same series, so a large room or reference-level movie bass may call for a second sub.
The case for the Monoprice 12in 150-Watt Powered: A very cheap 12 inch ported subwoofer that plays loud for the money, a simple first subwoofer for movies. The catch: Output drops off below about 50Hz, port chuffing becomes audible around 35Hz on bass drops, and a resonance near 100Hz was audible in outdoor testing.
Buy the SVS SB-3000 if sound quality is the priority over the price, or the Monoprice 12in 150-Watt Powered if the price is the priority over sound quality.
