Our take on the Monoprice 12" 150W Powered Subwoofer

The Monoprice 12-inch 150W Powered Subwoofer is a front-firing, ported bass box with a 150W RMS (200W peak) integrated amplifier and a rated 25–250 Hz response. It is a budget-minded way to add real low-end to a stereo or 5.1 setup, with a wooden cabinet, detachable grille and line-level and speaker-level inputs. Against small sealed subs it digs deeper and plays louder, but it is a big, heavy 41.7 lb box and its bass is tuned more for movies than tight music. Owners rate it highly for value; critics note it can sound boomy and lacks the refinement of pricier subs.
