Short answer: the Rythmik F12. It ranks #21 of 212 subwoofers by sound quality (rated 4.1/5) at $1,439 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.
What the Rythmik F12 does well: A sealed servo subwoofer with deep, musical bass and excellent build quality, a strong value for music lovers. The tradeoff: The sealed 12-inch driver cannot reproduce the deepest cinema effects, so a pair is advised for theater.
Why pick the Power Sound Audio (PSA) XS15SE: 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 Rythmik F12. It is rated higher for sound quality, and the Power Sound Audio (PSA) XS15SE is discontinued, so it is only available used.
