For sound you can feel.
The Yamaha MSR800W powered subwoofer is the perfect companion for the MSR400 (sold separately), extending the low end and completing the musical spectrum for maximum punch and impact. The high-quality birch plywood bass-reflex cabinet houses a 15" cone woofer powered by an ultra efficient burst 800W amplifier, a configuration that can deliver the elusive 40Hz-120Hz frequency range with precision and authority. 2 balanced XLR connectors are provided for connection to the source, and that same signal can be directly passed on to the main speakers via the XLR thru outputs. Alternatively, the main speakers can be fed by the MSR800W's dual HIGH PASS outputs--high-pass filtered at 80Hz-100Hz, depending on the setting of the cutoff frequency control--with a steep 18dB/octave cutoff slope. The Yamaha subwoofer also features LED power and clip indicators.
