Short answer: both are discontinued, and they are rated the same for sound quality (#84 and #89 of 143 subwoofers). Either one is only an option used, so choose on condition and price. If you want one new, the SVS SB17-Ultra R-Evolution replaces the SVS SB16-Ultra and is rated 4.1/5 at $2,699.
What the Power Sound Audio (PSA) XV15SE does well: A big rear ported 15 inch subwoofer with huge deep bass output for movies in a large room, now discontinued but worth buying used. The tradeoff: The 584.2H x 431.8W x 558.8D mm cabinet and 82.9 lbs (37.6 kg) mass make this a serious placement and moving commitment.
What the SVS SB16-Ultra does well: A sealed 16 inch subwoofer with forceful, punchy bass for movies and music, now discontinued but worth buying used. 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 Power Sound Audio (PSA) XV15SE or the SVS SB16-Ultra, whichever you find used in better condition; both are discontinued. For a new speaker, buy the SVS SB17-Ultra R-Evolution, which replaces the SVS SB16-Ultra.
