#9 JTR Speakers Captivator S2: $3,995 Discontinued eBay
Pros: A tall sealed subwoofer with two 18 inch drivers and serious deep bass output for demanding movies in a large room. Independent CEA-2010 testing records 115.1 dB at 20 Hz and 129.4 dB through 40-80 Hz. The sealed enclosure with 2x 18” (457mm) drivers has the headroom for demanding film bass in a large room.
Cons: The 1016.0H x 533.4W x 457.2D mm cabinet and 99.8 kg mass make this a serious placement and moving commitment. A sealed cabinet still needs careful placement and calibration to avoid room-mode peaks. Discontinued.
Notes: Replaced by “RS2”
