M2D™ compact curvilinear array loudspeaker brings numerous advantages to mid-sized venues that require tight vertical pattern control with medium-to-long throw. Its operating frequency range is 60 Hz to 16 kHz, with maximum peak output of 136 dB SPL (each cabinet) at 1 meter.
The M2D is designed for implementing vertical curvilinear arrays of up to 16 cabinets with 1- to 7-degree splay between adjacent units. For maximum leeway in configuring systems, the M2D is fully compatible with other M Series models and many Concert Series and UltraSeries™ loudspeakers.
The M2D uses Meyer Sound’s patented REM™ ribbon emulation manifold to couple a single Meyer Sound 4-inch diaphragm (1.5-inch exit) compression driver to a 90-degree horn with constant-directivity horizontal coverage. REM controls the output of the compression driver and introduces it to the horn throat within a 3-inch path length, dramatically reducing distortion. The unique M2D horn design produces a coherent wave front that is characteristic of – but much more powerful than – a large ribbon driver. (Vertical coverage depends upon array length and curvatureThe M2D's low-mid section comprises two Meyer Sound 10-inch cone drivers with lightweight neodymium magnet assemblies housed in a compact, vented trapezoidal enclosure. The M2D enclosure is constructed of multi-ply hardwood and coated with a textured black finish. Integral metal grilles protect the drivers. A weather-protected version with custom rain hood to protect the electronics is optionally available.
To assure the smoothest response in the midrange, the M2D incorporates a complex crossover design; at the lowest frequencies, both 10-inch drivers combine to reproduce powerful, coherent bass, while in the mid frequencies the crossover feeds only one of the two drivers. This technique eliminates interference between the drivers that would otherwise occur at shorter wavelengths, and maintains optimal polar and frequency response characteristics.
The self-powered, biamplified M2D incorporates a complementary MOSFET power amplifier with 700 watts burst capability, together with active crossover and optimized frequency and phase response correction circuitry. Its Intelligent AC™ system performs automatic voltage selection, allowing the unit to accommodate mains voltages in the range of 90 to 265 V AC at 50 or 60 Hz and additionally provides EMI filtering, soft current turn-on and surge suppression. Integral peak and rms limiters protect the loudspeaker components from over-excursion and over-heating. 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.
QuickFly® rigging, fitted as standard, employs entirely captive hardware and allows flying up to 16 cabinets with a 7:1 safety factor. The optional MG-2D multipurpose grid allows loudspeakers to be flown or ground stacked. The M2D features Meyer Sound’s RMS™ remote monitoring system, which allows the full range of operating parameters to be monitored continuously over a network using a Windows computer.
The companion M2D-Sub compact subwoofer is also available to provide low-frequency enhancement and extend overall system power bandwidth and frequency response to 30 Hz.
