At high frequencies, Meyer Sound's patented REM ribbon emulation manifold feeds a constant-directivity horn from two Meyer Sound compression drivers. REM controls the drivers’ output and introduces it to the horn throat within a 3-inch path length, dramatically minimizing distortion. The Meyer Sound M3D horn design produces a coherent wave front that is characteristic of — but much more powerful than — a large ribbon driver. Vertical coverage is restricted to approximately 10 degrees and interaction minimized, yet distortion remains extremely low.

At the lowest frequencies, two front-facing, long-excursion 15-inch drivers combine to reproduce powerful, coherent bass. A proprietary system of rear-facing low drivers, separately driven by a complex phase manipulation circuit, generates a wave front that interacts with that produced by the front-facing low drivers, affording directional low-frequency output to 35 Hz with a 90-degree polar pattern and 25 dB reduction in sound level behind the cabinet. In the mid frequencies, the integral crossover feeds only one of the two front drivers, eliminating interference that would occur at shorter wavelengths, and maintaining optimal polar and frequency response characteristics.

The self-powered Meyer Sound M3D produces a maximum output of 145 dB peak SPL at 1 meter within its operating frequency range of 35 Hz to 18 kHz. The amplifier, control electronics and power supply are integrated into a single, field-replaceable module mounted at the rear of the cabinet. The four-channel class AB/H power amplifier with complementary MOSFET output stages produces 4500 watts maximum. The Meyer Sound M3D’s Intelligent AC™ power supply affords automatic voltage selection, EMI filtering, soft current turn-on and surge suppression. Phase-corrected active processing circuits help maintain excellent performance and reliability, and the high common-mode rejection of the laser-trimmed differential input permits long signal runs through a simple shielded twisted pair cable.

The Meyer Sound M3D cabinet is coated with a textured black finish. Integral metal grilles protect the cone drivers, and a rain hood is fitted to protect the electronics from moisture intrusion.
