JTR Speakers Captivator 2400: $3,500 JTR Speakers eBay

Pros: Independent CEA-2010 testing records 115.5 dB at 20 Hz and 126.2 dB through 40-80 Hz. The ported, front enclosure with 18” (457mm) driver has the headroom for demanding film bass in a large room.

Cons: The 762.0H x 508.0W x 571.5D mm cabinet and 67.1 kg mass make this a serious placement and moving commitment. Ported output does not solve room modes, so careful placement and calibration remain essential.
