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 40° beamwidth. The LF woofers
shall be optimally spaced to provide significant off-axis atten-
uation 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 produc-
ing 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 111 dB SPL on axis at 1 meter with a power input of 1 watt,
and shall be capable of producing a peak output of 143 dB SPL
on axis at 1 meter. The HF section shall produce a sound pres-
sure level of 111 dB SPL on axis at 1 meter with a power input
of 1 watt, and shall be capable of producing a peak output of
139 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 amplifier power (AES Standard) and shall have a
nominal impedance 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 finished in
wear-resistant textured black paint. Input connectors 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
MQH1344e.
Manufacturing tolerances are +/- 0.13 and +/- 1°
