ARCHITECTURAL SPECIFICATIONS
The two-way mid/high loudspeaker system shall incorporate
a 10-in cone MF transducer and a 2-in exit compression driver
HF transducer.
The MF driver shall be loaded into a midrange horn con-
structed of 3mm birch plywood reinforced with high density
polyurethane foam. The MF horn shall incorporate a phase/
displacement plug. The HF driver shall be loaded on con-
stant directivity horn with a nominal coverage pattern of
90° (h) x 40° (v). An internal passive filter network shall
provide system equalization.
System frequency response shall vary no more than ±3 dB
from 190 Hz to 19 kHz measured on axis. The midrange fre-
quency section shall produce a Sound Pressure Level (SPL) of
108.5 dB SPL on axis at 1 meter with a power input of 1
Watt, and shall be capable of producing a peak output of
140.5 dB SPL on axis at 1 meter. The high frequency section
shall produce a Sound Pressure Level (SPL) of 110.5 dB SPL
on axis at 1 meter with a power input of 1 Watt, and shall be
capable of producing a peak output of 139.5 dB SPL on axis
at 1 meter. The midrange frequency section shall handle 400
Watts of amplifier power (AES Standard) and shall have a
nominal impedance of 8 Ohms. The high frequency section
shall handle 200 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 15mm thickness void-free cross-grain-
laminated Baltic birch plywood and shall employ extensive
internal bracing. It shall be finished in black catalyzed poly-
urethane. Input connectors shall be 4-terminal barrier strip
and one Neutrik NL4 Speakon. A total of sixteen 3/8"-16
threaded mounting/suspension points (4 each top, bottom
and sides) shall be provided. The front of the loudspeaker
shall be covered with a powder coated perforated steel grill.
The two-way mid/high loudspeaker shall be the EAW model
MQ1394.
