GSR18A 00633218

Developed by the same engineering team behind our industry-leading reference monitors, the M-Audio® GSR18 active subwoofer adds serious low end to any full-range satellite speaker system. The 18 inch. low-frequency driver and ultra-efficient Class D amplifier produce an impressive 500 watts of power for bass you can really feel. The variable crossover lets you dial in the perfect balance between the subwoofer and your full-range speakers for incredibly flat frequency response, while the phase invert button ensures that you get full, focused bass-regardless of stage position. The durable plywood enclosure and steel grille are designed to withstand the demands of constant use.
