Meyer Sound's patented MTS-4A is a self-powered, four-way loudspeaker system uniquely capable of producing very high sound levels across the full audio range, including lower fundamentals and sub-harmonics. Powerful, yet relatively compact at 17 cubic ft., the MTS-4A offers an integrated solution for many applications — often eliminating the need for subwoofers and associated electronics.

The MTS-4A comprises four drivers, four amplifier channels affording 2480 watts total peak output (620 watts/channel) and a four-way, phase-corrected active crossover network. The control electronics are optimized to allow the 12-inch, 15-inch and 18-inch drivers to operate together over the critical 60 Hz to 100 Hz frequency band, affording maximum power and precise definition. The 4-inch diaphragm high-frequency compression driver extends high-frequency response to 18 kHz, with phase response flat to 12 kHz.

All four amplifier channels operate class AB/H and employ complementary MOSFET output stages. For maximum driver protection and extended component life, the amplifier modules incorporate TruPower limiting technology. Intelligent AC provides automatic voltage selection, EMI filtering, soft current turn-on and surge suppression.

The trapezoidal cabinet is constructed of multi-ply hardwood with a hard, textured black finish. The MTS-4A is compatible with Meyer Sound’s RMS remote monitoring system, which provides comprehensive monitoring of system performance parameters over a Windows-based network.
