Large Home Subwoofers (Over 75 lbs)
Ranked #107 of 109 in Large Home Subwoofers (Over 75 lbs) - BK Electronics Monolith-DF: $8995 Discontinued eBay
Pros: Independent CEA-2010 testing records 102.0 dB at 20 Hz and 108.4 dB through 40-80 Hz. The ported, bottom enclosure with 12” (305mm) driver with ported design 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 603.8H x 539.8W x 419.9D mm cabinet and 46.8 kg mass still require deliberate placement and calibration. Discontinued.
