ARCHITECTURAL SPECIFICATIONS
The 3-way full-range loudspeaker shall incorporate 2x 15-in
slot-loaded woofers, a 10-in MF cone with Radial Phase Plug™,
and a 2-in exit/3-in diaphragm HF compression driver. The
MF and HF devices shall be loaded on asymmetrical, down-
angled horns with a 40
°
x 60
°
beamwidth. The LF woofers
shall be optimally spaced to provide significant off-axis at-
tenuation to below 200 Hz.
System frequency response shall vary no more than 63 dB
from 75 Hz to 15 kHz measured on axis. The lower LF section
shall produce a sound pressure level of 92 dB SPL on axis at
1 meter with a power input of 1 watt, and shall be capable
of producing a peak output of 126 dB SPL on axis at 1 meter.
The upper LF section shall produce a sound pressure level of
94 dB SPL on axis at 1 meter with a power input of 1 watt,
and shall be capable of producing a peak output of 128 dB
SPL on axis at 1 meter. The MF section shall produce a sound
pressure level of 110 dB SPL on axis at 1 meter with a power
input of 1 watt, and shall be capable of producing a peak
output of 142 dB SPL on axis at 1 meter. The HF section
shall produce a sound pressure level of 109 dB SPL on axis at
1 meter with a power input of 1 watt, and shall be capable
of producing a peak output of 137 dB SPL on axis at 1 meter.
Both LF sections shall handle 600 watts of amplifier power
(AES Standard) and shall have a nominal impedance of 8
ohms. The MF section shall handle 400 watts of amplifier
power (AES Standard) and shall have a nominal impedance
of 8 ohms. The HF section shall handle 150 watts of ampli-
fier power (AES Standard) and shall have a nominal imped-
ance of 8 ohms.
The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of exterior grade Baltic birch plywood
and shall employ extensive internal bracing. It shall be fin-
ished in wear-resistant textured black paint. Input connec-
tors shall be a terminal strip. A total of 16x 3/8”-16 threaded
mounting/suspension points (4 each top, bottom, and sides)
shall be provided. The front of the loudspeaker shall be cov-
ered with a powder coated perforated steel grille.
The 3-way full-range loudspeaker shall be the EAW model
MQH1346e.
