Definitive Technology SuperCube 2000: $599 Discontinued eBay
Pros: 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.

GoldenEar ForceField 3: $650 Discontinued eBay
Pros: Independent CEA-2010 testing records 110.2 dB (avg of 3/4 bands) through 40-80 Hz. The passive radiator 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 292.1H x 288.8W x 400.0D mm cabinet and 11.8 kg mass still need careful placement and calibration. Discontinued.
