SVS 3000 Micro: $999.00 Amazon eBay
Pros: Independent CEA-2010 testing records 90.6 dB at 20 Hz and 113.5 dB through 40-80 Hz. The sealed enclosure with 2x 8” (203mm) 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 276.9H x 297.2W x 271.8D mm cabinet and 10.2 kg mass still require deliberate placement and calibration.
