Short answer: the KEF KC62, if you are buying new. The Power Sound Audio (PSA) XV15 ranks higher than it (#10 vs #212 of 212 subwoofers, 4.1/5 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) XV15 is the better-sounding option. A down firing 15 inch ported subwoofer with deep, clean, detailed bass that plays loud, now discontinued but worth buying used. The tradeoff: It weighs 75 lbs (34.0 kg) in a 584 x 432 x 559 mm cabinet, so it needs a lot of space.
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 catch: 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 if you want one new; the Power Sound Audio (PSA) XV15 is discontinued, so only look for it used.
