JTR Speakers Captivator 1400 vs SVS SB13-Plus

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 #142 (rated 3.3/5) for the SVS SB13-Plus. If you want one new, the Monoprice Monolith M-215 ranks #24 at $2,999.99.

The JTR Speakers Captivator 1400 is the better-sounding pick. A low, wide 18 inch ported subwoofer with strong deep bass for movies, easy to tuck under a screen or riser. Watch for: 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 SB13-Plus: A sealed 13 inch subwoofer with XLR and RCA inputs in a compact cube cabinet, now discontinued. Watch for: 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 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, start with the Monoprice Monolith M-215 instead.
