Constant-Q horn assures uniform coverage
Unique crossover design eliminates mid-range combing
•  Theatrical sound reinforcement
Portable and installed audio-visual systems
Compact voice reinforcement systems
Front and under-balcony fill

The M1D Ultra-Compact Curvilinear Array loudspeaker (patent pending) brings numerous advantages in sound reinforcement for small venues. The M1D is designed specifically for implementing vertical curvilinear arrays of up to 16 cabinets having 0° to 8° splay between adjacent units. Housed in a compact, vented trapezoidal enclosure, the M1D comprises two 5-inch drivers for low-mid frequencies, and three 1-inch high-frequency dome tweeters coupled to a constant-directivity horn. Its operating frequency range is 60 Hz to 18 kHz, with maximum peak output of 125 dB SPL (each cabinet) at 1 meter and coverage of 100° horizontal (vertical coverage depends upon the array length and curvature).M1D : Ultra-Compact Curvilinear Array

To assure the smoothest response in the critical midrange, the M1D incorporates a complex crossover design similar to that pioneered in Meyer Sound’s UPM loudspeakers. At the lowest frequencies, both 5-inch drivers combine to reproduce powerful, coherent bass. 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, and maintains optimal polar and frequency response characteristics.

The self-powered, biamplified M1D incorporates a complementary MOSFET power amplifier module with prodigious burst capability, together with an 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. Integral peak and RMS limiters employing Meyer Sound’s TruPower limiting technology protect the loudspeaker components from over-excursion and overheating.
