SVS SB13-Plus vs JTR Speakers Growler (2015)

Last updated: October 21, 2026

Short answer: both are discontinued, so this only matters if you are buying used. Used, the JTR Speakers Growler (2015) is the better pick: it ranks #13 of 143 subwoofers by sound quality (rated 4.5/5), against #142 (rated 3.3/5) for the SVS SB13-Plus. If you want one new, the JTR Speakers Captivator 215PRO ranks #7 at $3,500.

SVS SB13-Plus vs JTR Speakers Growler (2015)

What the SVS SB13-Plus does well: A sealed 13 inch subwoofer with XLR and RCA inputs in a compact cube cabinet, now discontinued. The catch: 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.

The JTR Speakers Growler (2015) is the better-sounding choice. A 12 inch ported subwoofer with output close to far bigger flagships, a strong used pick now that it is discontinued. The tradeoff: Ported design room interaction, 99.2 lbs (45 kg) size, and $2995 cost.

Buy the JTR Speakers Growler (2015) 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 Captivator 215PRO instead.
