Monoprice SW-15 vs Power Sound Audio (PSA) XS15-BASE

Last updated: October 27, 2026

Short answer: the Monoprice SW-15, if you are buying new. The Power Sound Audio (PSA) XS15-BASE measures as well as it (#17 vs #14 of 212 subwoofers, 4.1/5 vs 4.1/5) but is discontinued, so only consider it used; the Monoprice SW-15 is still sold new at $499.99.

Monoprice SW-15 vs Power Sound Audio (PSA) XS15-BASE

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. The tradeoff: Budget-tier design, ported room gain dependency, 66.1 lbs (30 kg) mid-size, and limited dynamic headroom.

The case for the Power Sound Audio (PSA) XS15-BASE: A sealed 15 inch subwoofer in a heavier base cabinet with strong, controlled bass, now discontinued but worth buying used. Watch for: Output at 20Hz and below is about 107dB, much lower than in the midbass, so the deepest effects are limited.

Buy the Monoprice SW-15 new; the Power Sound Audio (PSA) XS15-BASE is no longer sold new, so it only makes sense as a used find.
