Short answer: both are discontinued, so this only matters if you are buying used. Used, the Harbinger V2218S is the better pick: it ranks #15 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.
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 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.
The Harbinger V2218S is the better-sounding choice. A pro style 18 inch ported subwoofer with hard hitting upper bass for movie effects and music, relatively light for its output. 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.
Buy the Harbinger V2218S 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.
