Short answer: the Power Sound Audio TV2112. Both are rated 4.4/5 for sound quality (#27 and #24 of 143 subwoofers), and the Power Sound Audio TV2112 costs $2,499 against $2,999.99 for the Monoprice Monolith M-215, and with sound quality even, the cheaper one is the better buy.
Why pick the Monoprice Monolith M-215: Independent CEA-2010 testing records 118.9 dB at 20 Hz and 125.9 dB through 40-80 Hz. Watch for: The 1074.4H x 508.0W x 701.0D mm cabinet and 216.1 lbs (98.0 kg) mass make this a serious placement and moving commitment.
Why pick the Power Sound Audio TV2112: A true reference-grade super-subwoofer housing a pro-audio 21-inch Italian neodymium woofer powered by a 1,920W ICEpower amplifier. The tradeoff: Enormous physical footprint (864 x 610 x 762 mm) and 170 lbs (77.1 kg) mass require dedicated floor space and a two-person lift.

Monoprice Monolith M-215: $2999.99 Monoprice eBay
Same family: the Monoprice Monolith M-210 (smaller subwoofer, ranked lower, rated 3.9/5) and the Monoprice Monolith M-212 (smaller subwoofer, ranked lower, rated 4.2/5).
Pros: Independent CEA-2010 testing records 118.9 dB at 20 Hz and 125.9 dB through 40-80 Hz. The ported, front enclosure with 2x 15” (381mm) drivers has the headroom for demanding film bass in a large room.
Cons: The 1074.4H x 508.0W x 701.0D mm cabinet and 98.0 kg mass make this a serious placement and moving commitment. Ported output does not solve room modes, so careful placement and calibration remain essential.
