Perlisten Audio D215s: $9,000 eBay
Pros: Independent CEA-2010 testing records 109.2 dB at 20 Hz and 123.2 dB through 40-80 Hz. The sealed enclosure with 2x 15” (381mm) drivers has the headroom for demanding film bass in a large room.
Cons: The 805.2H x 500.4W x 650.2D mm cabinet and 91.8 kg mass make this a serious placement and moving commitment. A sealed cabinet still needs careful placement and calibration to avoid room-mode peaks.
