Short answer: the SVS SB-1000 PRO on measured sound quality, the Klipsch HD Theater 600 on price. The SVS SB-1000 PRO ranks #4 of 48 subwoofers at $599. The Klipsch HD Theater 600 ranks #25 at $399, $200 cheaper.
What the SVS SB-1000 PRO offers: 12-inch sealed driver delivers 113.9dB CEA-2010-A average, the highest output of any subwoofer in the under-30lb weight class. Sealed enclosure keeps bass tight and controlled for its compact footprint. Watch for: Compact ported design, room mode sensitivity, limited to 114 dB output, smaller than alternatives.
What the Klipsch HD Theater 600 offers: Independent CEA-2010 testing records 108.2 dB (avg of 3/4 bands) through 40-80 Hz. The ported, rear enclosure with 8” (203mm) driver is a compact way to add useful midbass support to a modest system. Watch for: Without a published 20 Hz result, deep-bass capability is less certain than the midbass figure. The 353.1H x 317.5W x 317.5D mm cabinet and 7.7 kg mass still need careful placement and calibration.
Buy the SVS SB-1000 PRO if sound quality is the priority over the price, or the Klipsch HD Theater 600 if the price is the priority over sound quality.
