Short answer: both are discontinued, so this only matters if you are buying used. Used, the Definitive Technology SuperCube 8000 is the better pick: it ranks #40 of 167 subwoofers by sound quality (rated 3.9/5), against #8 (rated 3.7/5) for the Definitive Technology SuperCube 2000. If you want one new, the SVS SB-3000 R|Evolution ranks #3 at $1,299.99.
The case for the Definitive Technology SuperCube 8000: Fills large spaces with loud, extended musical bass in just 1.8 sq ft footprint.
Why pick the Definitive Technology SuperCube 2000: Independent CEA-2010 testing records 80.1 dB at 20 Hz and 114.2 dB through 40-80 Hz. The catch: 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.
Buy the Definitive Technology SuperCube 8000 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the SVS SB-3000 R|Evolution instead.

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.
