Short answer: the Monoprice SW-15. It ranks #14 of 212 subwoofers by sound quality (rated 4.1/5) at $499.99 and is still sold new; the Power Sound Audio (PSA) XS15SE ranks #30 (rated 3.9/5) and is discontinued, so it is only an option used.
The case for the Monoprice SW-15: A big 15 inch subwoofer with powerful, punchy bass at a budget price, great for movies in a large room. Watch for: Budget-tier design, ported room gain dependency, 66.1 lbs (30 kg) mid-size, and limited dynamic headroom.
Why pick the Power Sound Audio (PSA) XS15SE: A compact sealed 15 inch subwoofer with strong output for movies and music, now discontinued. The tradeoff: 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.
