SVS SB-2000 Pro: $899.00 each Amazon eBay
Older models: the SVS SB-2000 (ranked higher, rated 3.9/5) and the SVS SB12-Plus (ranked lower, rated 3.6/5).
Pros: A compact sealed 12-inch subwoofer, about 37cm on each side, with a 550W RMS (1,500W peak) Sledge amplifier and SVS’s smartphone app for volume, crossover, phase, room gain compensation and parametric EQ from the listening seat. Erin’s Audio Corner measured a 114.7dB CEA-2010-A average from 40 to 80Hz, and SVS rates it at 19-240Hz within 3dB.
Cons: Output is modest next to larger or ported subwoofers: Erin’s Audio Corner measured about 102.5dB at 20Hz, and he judged the SB-3000, about $200 more, the better value for its considerably higher output. Sealed designs this size run out of headroom sooner in large rooms.
