#56 JTR Speakers Captivator RS1: $3,300 JTR Speakers $3,300 eBay

Pros: A compact sealed 18 inch subwoofer with strong deep bass for home theater and both balanced and RCA inputs. Independent CEA-2010 testing records 111.1 dB at 20 Hz and 121.8 dB through 40-80 Hz. The sealed enclosure with 18” (457mm) driver has the headroom for demanding film bass in a large room.

Cons: The 533.4H x 533.4W x 457.2D mm cabinet and 53.1 kg mass make this a serious placement and moving commitment. A sealed cabinet still needs careful placement and calibration to avoid room-mode peaks.
