MILO 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 eld frequency
response
65 Hz - 17.5 kHz ±4 dB
Note: Measured with 1/3 octave frequency resolution at 4 meters.
Phase response 750 Hz - 16 kHz ±30°
Maximum peak SPL 140 dB @ 1 m
Note: Measured with music at 1 meter.
Dynamic range >110 dB
Horizontal coverage 90°
Vertical coverage Varies, depending on array length and conguration.
Acoustical crossover 560 Hz, 4.2 kHz
Note: At these frequencies, the transducers produce equal sound pressure levels: 560 Hz
for the low-mid and mid-high and 4.2 kHz for the mid-high and very-high frequency drivers.
TRANSDUCERS
Low/low-mid frequency Two 12" cone drivers with neodymium magnets
Nominal impedance: 4 Ω
Voice coil size: 4"
Power-handling capability: 1200 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 12-inch drivers work in combination at low frequencies (60
Hz – 300 Hz). At mid frequencies (300 Hz – 560 Hz) only one cone driver is fed from the crossover to maintain optimal
polar and frequency response characteristics. Attenuation on the other driver: -6 dB at 300 Hz, -12 dB at 400 Hz, -18 db
at 500 Hz.
Mid-high frequency One 4" compression driver
Nominal impedance: 8 Ω
Voice coil size: 4"
Diaphragm size: 4"
Exit size: 1.5"
Power handling capability: 250 W (AES) on REM
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 driver is coupled to a constant-directivity horn through a proprietary acoustical combining manifold (REM).
Very-high frequency Three 2" compression drivers
Nominal impedance: 12 Ω
Voice coil size: 2"
Diaphragm size: 2"
Exit size: 0.75"
Power handling capability: 100 W (AES) on REM
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 through a proprietary acoustical combining manifold
(REM).
