Short answer: the KEF KC62, if you are buying new. The Power Sound Audio (PSA) XS15SE ranks higher than it (#30 vs #212 of 212 subwoofers, 3.9/5 vs 2.5/5) but is discontinued, so only consider it used; the KEF KC62 is still sold new at $1,579.95.
The Power Sound Audio (PSA) XS15SE is the better-sounding option. A compact sealed 15 inch subwoofer with strong output for movies and music, now discontinued. Watch for: 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.
The case for the KEF KC62: A tiny sealed subwoofer with two opposing 6.5 inch drivers and placement EQ presets, sized to fit almost any room’s decor. The tradeoff: A hard limiter caps low bass as you turn it up: at 85 to 90dB it plays about 74dB at 20Hz, 6dB below the KEF KF92, and 10Hz output is about 15dB lower.
Buy the KEF KC62 new; the Power Sound Audio (PSA) XS15SE is no longer sold new, so it only makes sense as a used find.
