#16 Power Sound Audio (PSA) XS15: $1,299 Discontinued eBay

Newer model: the Power Sound Audio (PSA) XS15SE, ranked lower, rated 3.9/5, released Apr 2014 (also discontinued).

Same family: the Power Sound Audio (PSA) XS15SE (larger subwoofer, ranked lower, rated 3.9/5), the Power Sound Audio (PSA) XS30 (larger subwoofer, rated 4.3/5) and the Power Sound Audio (PSA) XS30SE (larger subwoofer, rated 4.2/5).

Pros: A sealed 15 inch subwoofer with strong output for large rooms and predictable bass that works well with room correction. It pairs a 15-inch sealed driver with a 550W RMS amplifier (1650W peak) and a rated response of 23 to 200Hz at plus or minus 3dB. The manufacturer’s output tests show 118.2dB from 40 to 63Hz, enough for a large room. The sealed design behaves predictably, which suits room correction.

Cons: Output drops to 107.1dB in the 20 to 31.5Hz bands, 11dB below the 40Hz range, and the test reports no data for the 80Hz band. Those figures come from the manufacturer rather than an independent lab. The cabinet weighs 26.8 kg and measures 495.3H x 431.8W x 457.2D mm. It is discontinued and has a newer replacement, so buying means finding one used.
