APPENDIX B: MICA SPECIFICATIONS
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.
Free field frequency
response
75 Hz - 17 kHz ±4 dB
Note: Measured with 1/3-octave frequency resolution at 4 meters.
Phase response 1 kHz - 16 kHz ±30°
Maximum peak SPL 138 dB
Note: Measured with music referred to 1 meter.
Dynamic range >110 dB
Horizontal coverage 100°
Vertical coverage Varies, depending on array length and configuration
Acoustical crossover 1000 Hz
Note: At this frequency, the transducers produce equal sound pressure levels.
TRANSDUCERS
Low/low-mid frequency Two high-power 10" cone drivers with neodymium magnets
Nominal impedance: 4 Ω
Voice coil size: 2"
Power handling capability: 1200 W (AES); 1800 W peak
Note: Power handling is measured under AES standard conditions: both transducers driven
continuously for two hours with band limited noise signal having a 6 dB peak-average ratio.
Peak power handling is measured with both transducers driven for 100 milliseconds with
pink noise signal having a 12 dB peak-average ratio.
Note: To eliminate interference at shorter wavelengths, the two 10-inch drivers work in
combination at lower frequencies (60 Hz - 320 Hz). At mid frequencies (320 Hz - 1000 Hz)
only one cone driver is fed from the crossover to maintain optimal polar and frequency
response characteristics.
High frequency Two 3" compression drivers
Nominal impedance: 8 Ω
Voice coil size: 3"
Diaphragm size: 3"
Exit size: 1.2"
Power handling capability: 360 W (AES); 720 W peak
Note: Power handling is measured under AES standard conditions: both transducers driven
continuously for two hours with band limited noise signal having a 6 dB peak-average ratio.
Peak power handling is measured with both transducers driven for 100 milliseconds with
pink noise signal having a 12 dB peak-average ratio.
Note: The two drivers are coupled to a 100-degree-horizontal constant-directivity horn through a proprietary acoustical
combining manifold (REM).
