Short answer: the Klipsch R-121SW, if you are buying new. The Power Sound Audio (PSA) XS15SE ranks higher than it (#30 vs #132 of 212 subwoofers, 3.9/5 vs 3.6/5) but is discontinued, so only consider it used; the Klipsch R-121SW is still sold new at $449.99.
Why pick the Klipsch R-121SW: A 12 inch front-firing subwoofer with Klipsch’s copper colored woofer, an affordable pick for home theater. Watch for: Output drops to 98.4dB at 25Hz and 96.0dB at 20Hz, so the deepest film effects will be weak in a large room.
What the Power Sound Audio (PSA) XS15SE does well: A compact sealed 15 inch subwoofer with strong output for movies and music, now discontinued. The catch: At 67 lbs (30.4 kg) and 495.3H x 431.8W x 457.2D mm it is heavy and sizeable even though it is sealed.
Buy the Klipsch R-121SW new; the Power Sound Audio (PSA) XS15SE is no longer sold new, so it only makes sense as a used find.
