JTR Speakers Captivator 2400 vs Reaction Audio PV-15X

Short answer: the JTR Speakers Captivator 2400, if you are buying new. The Reaction Audio PV-15X measures as well as it (#21 vs #20 of 110 subwoofers, 4.4/5 vs 4.4/5) but is discontinued, so only consider it used; the JTR Speakers Captivator 2400 is still sold new at $3500.

On the Reaction Audio PV-15X side: 15-inch ported driver delivers 126.2dB CEA-2010-A average from a purpose-built cinema-style cabinet. The catch: Passive design requires a separate external amplifier and weighs 68 kg (149.9 lbs).

Buy the JTR Speakers Captivator 2400, since the Reaction Audio PV-15X is discontinued and only worth hunting down used.

JTR Speakers Captivator 2400: $3,500 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.
