Buy the MartinLogan Dynamo 700w, since the Definitive Technology SuperCube 2000 is discontinued and only worth hunting down used.

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.
