INTRODUCING THE M2D AND M2D-SUB LOUDSPEAKERS

As part of Meyer Sound’s M Series, the M2D compact curvilinear array loudspeaker and M2D-Sub compact subwoofer bring numerous advantages to mid-sized venues that require tight vertical pattern control with long throw. Self-powered, with QuickFly® rigging and Meyer Sound’s RMS™ remote monitoring system as standard, the M2D and M2D-Sub loudspeakers can be deployed as a self- contained system or configured along with other Meyer Sound loudspeakers in more complex systems.

Operating at a frequency range of 60 Hz to 16 kHz, the M2D loudspeaker’s compact enclosure (Figure i.1) is designed specifically for vertical curvilinear arrays of up to 16 cabinets having 0- to 7-degree splay between units in 1-degree increments.

The M2D loudspeaker gives you the flexibility to tailor vertical coverage by varying the number and splay of cabinets in the array while maintaining a constant 90 degrees of horizontal coverage. For high frequencies, the M2D loudspeaker utilizes Meyer Sound’s patented REM™ ribbon emulation manifold to couple a single compression driver with a 1.5-inch exit (4-inch diaphragm) to a horn with 90-degree constant-directivity horizontal coverage. (The vertical coverage of the array depends upon the array length and curvature). The M2D loudspeaker’s mid-low section comprises two high-power 10-inch drivers with lightweight neodymium magnet assemblies housed in a compact, vented trapezoidal enclosure.

In addition, to assure the smoothest response in the critical midrange, the M2D loudspeaker 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 ingenious technique eliminates interference between the drivers that would otherwise occur at shorter wavelengths near the crossover frequencies.

The companion M2D-Sub subwoofer (Figure i.2), designed specifically to work with the M2D, extends overall system power bandwidth and frequency range down to 28 Hz.
