Power Sound Audio (PSA) TRIAX: $7995 eBay
Pros: Published CEA-2010 specifications list 119.8 dB at 20 Hz and 130.9 dB (avg of 3/4 bands) through 40-80 Hz. The sealed enclosure with 3x 15” (381mm) driver has the headroom for demanding film bass in a large room.
Cons: The 596.9H x 787.4W x 698.5D mm cabinet and 104.3 kg mass make this a serious placement and moving commitment. A sealed cabinet still needs careful placement and calibration to avoid room-mode peaks.
