Short answer: the Magico Audio ASUB, if you are buying new. The JTR Speakers Captivator S2 ranks higher than it (#9 vs #137 of 143 subwoofers, 4.5/5 vs 3.6/5) but is discontinued, so only consider it used; the Magico Audio ASUB is still sold new at $9,000.
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 Magico Audio ASUB: A compact luxury sealed 10 inch subwoofer with XLR and RCA inputs plus a through output. 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 Magico Audio ASUB new; the JTR Speakers Captivator S2 is no longer sold new, so it only makes sense as a used find.
