#35 Klipsch HD Theater 600: $399 Discontinued eBay

Pros: A discontinued compact ported 8 inch subwoofer that adds midbass support to a small home theater system. 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.

Cons: 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. Discontinued.
