Short answer: the SVS SB-3000 for accuracy and output, the Klipsch R-121SW for the far lower price. The SB-3000’s 13-inch sealed cabinet and 800W RMS (2500W peak) amplifier average 118.7dB with exceptional accuracy and rank #15 of 212 medium subwoofers, though it costs $1,199 and its compact 25 kg (55.1 lbs) size limits bass extension. The R-121SW costs $389.99 with a 12-inch spun-copper driver and 200W RMS.
