Monoprice SW-15 vs PSB Speakers SubSeries 250

Last updated: October 27, 2026

Short answer: the Monoprice SW-15. It ranks #14 of 212 subwoofers by sound quality (rated 4.1/5) at $499.99 and is still sold new; the PSB Speakers SubSeries 250 ranks #104 (rated 3.7/5) and is discontinued, so it is only an option used.

Monoprice SW-15 vs PSB Speakers SubSeries 250

The Monoprice SW-15 is the better-sounding pick. A big 15 inch subwoofer with powerful, punchy bass at a budget price, great for movies in a large room. Watch for: Budget-tier design, ported room gain dependency, 66.1 lbs (30 kg) mid-size, and limited dynamic headroom.

Why pick the PSB Speakers SubSeries 250: A compact sealed 10 inch subwoofer for smaller rooms and tight spaces, now discontinued. The catch: Output at 31.5Hz is 102.2dB and 96.7dB at 25Hz, so it is not for large rooms or loud movie effects.

Buy the Monoprice SW-15. It is rated higher for sound quality, and the PSB Speakers SubSeries 250 is discontinued, so it is only available used.
