Short answer: both are discontinued, so this only matters if you are buying used. Used, the JTR Speakers Captivator S2 is the better pick: it ranks #9 of 143 subwoofers by sound quality (rated 4.5/5), against #30 (rated 4.3/5) for the JTR Speakers Captivator 1400. If you want one new, the JTR Speakers Orbit Shifter PRO ranks #1 at $4,499.
What the JTR Speakers Captivator S2 does well: 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.
The case for the JTR Speakers Captivator 1400: A low, wide 18 inch ported subwoofer with strong deep bass for movies, easy to tuck under a screen or riser. The tradeoff: The 508.0H x 762.0W x 571.5D mm cabinet and 142 lbs (64.4 kg) mass make this a serious placement and moving commitment.
Buy the JTR Speakers Captivator S2 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the JTR Speakers Orbit Shifter PRO instead.
