JTR Speakers Captivator 1400 vs SVS PB-4000

Short answer: both are discontinued, so this only matters if you are buying used. Used, the JTR Speakers Captivator 1400 is the better pick: it ranks #30 of 143 subwoofers by sound quality (rated 4.3/5), against #69 (rated 4.2/5) for the SVS PB-4000. If you want one new, the SVS PB-5000 R-Evolution replaces the SVS PB-4000 and is rated 4.2/5 at $2,399.

Why pick 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.

The case for the SVS PB-4000: A 13.5 inch ported subwoofer with very deep, strong bass for big home theaters and balanced and RCA inputs. The catch: The 594.4H x 520.7W x 703.6D mm cabinet and 153.2 lbs (69.5 kg) mass make this a serious placement and moving commitment.

Buy the JTR Speakers Captivator 1400 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, buy the SVS PB-5000 R-Evolution, which replaces the SVS PB-4000.
