The self-powered M3D features Meyer Sound’s state-of-the-art BroadbandQ technology. BroadbandQ marries a new high-frequency manifold system with proprietary, award-winning directional low-frequency technology to precisely control vertical and horizontal coverage between 35 Hz and 18 kHz. The result is truly optimized line array behavior, affording performance that is superior to conventional line array systems.

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 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.
