The Yamaha MSR400 is a bi-amplified, 2-way powered PA speaker designed for professional use. It uses a 12-inch low-frequency driver paired with a 1.75-inch compression driver for the highs, delivering up to 400 watts of output and a maximum sound pressure level of 121 dB. The speaker covers a frequency range of 50 Hz to 20 kHz (-10 dB) with a dispersion pattern of 90 degrees horizontal by 40 degrees vertical. Rear-panel EQ allows ±3 dB adjustment to the low frequencies at 55 Hz and ±3 dB to the highs. Mounting options include two M8-17 flying points and a standard 1-3/8 inch pole socket.
