JTR Speakers Captivator S2 vs XTZ Sound SUB 3X12

Short answer: the XTZ Sound SUB 3X12, if you are buying new. The JTR Speakers Captivator S2 ranks higher than it (#9 vs #28 of 143 subwoofers, 4.5/5 vs 4.3/5) but is discontinued, so only consider it used; the XTZ Sound SUB 3X12 is still sold new at $1,412.84.

Why pick the JTR Speakers Captivator S2: A tall sealed subwoofer with two 18 inch drivers and serious deep bass output for demanding movies in a large room. The catch: 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.

What the XTZ Sound SUB 3X12 does well: A triple 12 inch subwoofer with huge, deep output for movies in a large room, for less than most rivals. The catch: The 1158.2H x 535.9W x 556.3D mm cabinet and 170.6 lbs (77.4 kg) mass make this a serious placement and moving commitment.

Buy the XTZ Sound SUB 3X12 new; the JTR Speakers Captivator S2 is no longer sold new, so it only makes sense as a used find.
