#5 Definitive Technology SuperCube 2000: $599 Discontinued eBay

Same family: the Definitive Technology SuperCube 8000 (larger subwoofer, rated 3.9/5).

Pros: A discontinued very compact subwoofer with a 7.5 inch driver and passive radiator that adds upper bass punch to a small system. Independent CEA-2010 testing records 80.1 dB at 20 Hz and 114.2 dB through 40-80 Hz. The passive radiator enclosure with 7.5” (190mm) driver delivers substantial upper-bass output for movie effects and music.

Cons: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority. The 273.1H x 260.3W x 276.4D mm cabinet and 11.3 kg mass still require deliberate placement and calibration. Discontinued.
