JTR Speakers Captivator 215PRO: $3,500 eBay

Pros: Independent CEA-2010 testing records 106.6 dB at 20 Hz and 130.7 dB through 40-80 Hz. The ported, front enclosure with 2x 15” (381mm) drivers delivers formidable upper-bass output for movie effects and music.

Cons: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority. The 1016.0H x 457.2W x 762.0D mm cabinet and 67.6 kg mass still require deliberate placement and calibration.

Notes: Looks like “PA sub”

JTR Speakers Captivator S2: $3995 eBay

Pros: 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.

Notes: Replaced by “RS2”
