JTR Speakers Captivator S2 vs REL Acoustics HT/1510 Predator II

Short answer: the REL Acoustics HT/1510 Predator II, if you are buying new. The JTR Speakers Captivator S2 ranks higher than it (#9 vs #98 of 143 subwoofers, 4.5/5 vs 4.1/5) but is discontinued, so only consider it used; the REL Acoustics HT/1510 Predator II is still sold new at $1,799.

The JTR Speakers Captivator S2 is the better-sounding pick. A tall sealed subwoofer with two 18 inch drivers and serious deep bass output for demanding movies in a large room. Watch for: The 1016.0H x 533.4W x 457.2D mm cabinet and 220 lbs (99.8 kg) mass make this a serious placement and moving commitment.

The case for the REL Acoustics HT/1510 Predator II: A sealed 15 inch home theater subwoofer with strong, punchy upper bass for movie effects and music. The tradeoff: 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.

Buy the REL Acoustics HT/1510 Predator II, since the JTR Speakers Captivator S2 is discontinued and only worth hunting down used.
