Meyer M1D
|
The Meyer Sound M1D ultracompact curvilinear array loudspeaker brings the singular advantages of self-powered line arrays to sound reinforcement applications in small and mid-sized venues. The exceptionally compact enclosure enables sound designers to achieve high output, precise pattern control with very low distortion from a lightweight and unobtrusive system. The M1D provides a substantial peak SPL of 125 dB at 1 meter with an operating frequency range of 60 Hz to 18 kHz and is designed specifically for implementing vertical curvilinear arrays of up to 16 cabinets having 0- to 8-degree splay between adjacent units. This design affords the flexibility to tailor vertical coverage by varying the number and splay of cabinets in the array while maintaining a consistent 100° horizontal coverage.

Extremely compact and lightweight; forms virtually “invisible” PAs
Very flat response for exceptional accuracy and imaging
Constant-Q horn assures uniform coverage
Unique crossover design eliminates mid-range combing
Applications
Theatrical sound reinforcement
Portable and installed audio-visual systems
Compact voice reinforcement systems
Front and under-balcony fill
Acoustical
Note: The low-frequency power response of the system will increase according to the length of the array.
Operating frequency range: 60 Hz - 18 kHz
Note: Recommended maximum operating frequency range. Response depends upon loading conditions and room acoustics.
Frequency response: 75 Hz - 15 kHz ±4 dB
Phase response: 800 Hz - 12 kHz ±45°
Maximum peak SPL: 125 dB at 1 m
Note: Measured with music at 1 meter.
Dynamic Range: >110 dB
Horizontal coverage: 100°
Acoustical crossover: 1900 Hz
Note: At these frequencies, the transducers produce equal sound pressure levels.
Transducers
Low frequency:
Two 5" cone drivers
Nominal impedance: 8 Ω
Voice coil size: 1"
Power-handling capability: 200 W (AES)
Note: Power handling is measured under AES standard conditions: transducer driven continuously for two hours with band limited noise signal having a 6 dB peak-average ratio.
Note: To eliminate interference at short wavelengths, the two 5" drivers work in combination at low frequencies (60 Hz - 1000 Hz). At mid frequencies (1000 Hz - 1900 Hz) only one cone driver is fed from the crossover to maintain optimal polar and frequency response characteristics.
High frequency:
Three 0.75" metal dome tweeters with neodymium magnets
Nominal impedance: 8 Ω
voice coin size: 20 mm
Power-handling capability: 15 W (AES)
Note: Power handling is measured under AES standard conditions: transducer driven continuously for two hours with band limited noise signal having a 6 dB peak-average ratio.
Note: The three drivers are coupled to a constant-directivity horn.
