#47 JTR Speakers Captivator 2400ULF: $3,600 JTR Speakers $3,600 eBay

Pros: A tall 18 inch ported subwoofer tuned for very low bass, with strong output for large home theaters. Independent CEA-2010 testing records 115.6 dB at 20 Hz and 122.7 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 1041.4H x 520.7W x 571.5D mm cabinet and 74.8 kg mass make this a serious placement and moving commitment. Ported output does not solve room modes, so careful placement and calibration remain essential.
