Short answer: the Rythmik FV15HP. It ranks #55 of 143 subwoofers by sound quality (rated 4.2/5) at $2,127 and is still sold new; the SVS SB13-Plus ranks #142 (rated 3.3/5) and is discontinued, so it is only an option used.
The Rythmik FV15HP is the better-sounding choice. A 15 inch ported subwoofer with output matching pricier rivals, plus balanced and RCA inputs for flexible setups. The catch: Premium price ($2127), ported design room gain dependency, and mid-to-large 114.6 lbs (52 kg) footprint.
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 Rythmik FV15HP. It is rated higher for sound quality; the SVS SB13-Plus is no longer sold new.
