The bi-amplified or passive mid/high loudspeaker system
shall incorporate a horn-loaded 10-in MF cone with Radial
Phase Plug™ and a 1.4-in exit/2.5-in voice coil HF neodymi-
um compression driver.
The MF driver shall be loaded into a midrange horn con-
structed of 1/8-in birch plywood backed with high density
polyurethane foam. The HF driver shall be loaded on a con-
stant directivity horn with a nominal coverage pattern of 90°
(h) x 45° (v). An internal passive filter network shall provide
fourth order acoustical crossover and system equalization.
System frequency response shall vary no more than ±3 dB
from 200 Hz to 15 kHz measured on axis. The mid/high sec-
tion shall produce a Sound Pressure Level (SPL) of 107 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. The mid frequency section system shall produce a
Sound Pressure Level (SPL) of 109 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 141 dB SPL on axis at 1 meter. The high
frequency section shall produce a Sound Pressure Level (SPL)
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 136 dB
SPL on axis at 1 meter. The mid/high section shall handle
450 Watts of amplifier power (continuous) and shall have a
nominal impedance of 8 Ohms. The mid frequency section
shall handle 400 Watts of amplifier power (continuous) and
shall have a nominal impedance of 8 Ohms. The high fre-
quency section shall handle 125 Watts of amplifier power
(continuous) and shall have a nominal impedance of 8 Ohms.
The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of multi-ply, void-free, cross-grain-lami-
nated, exterior grade, Baltic birch plywood and shall employ
extensive internal bracing. It shall be finished in wear-resist-
ant textured black paint. Input connectors shall be 2x 6-con-
tact terminal barrier strips. Eighteen (18) 3/8"-16 threaded
mounting/suspension points (4 each top, bottom and sides,
2 on back) shall be provided. The front of the loudspeaker
shall be covered with a powder coated perforated steel grille.
The mid/high loudspeaker shall be the EAW model AS490e.
