ARCHITECTURAL SPECIFICATIONS
The 3-way fullrange loudspeaker systems shall incorporate
2x 15-in LF transducers, 2x 7-in cone MF transducers and a
1-in exit compression driver HF transducer.
The LF drivers shall be mounted in a vented enclosure tuned
for optimum low frequency response. The MF drivers shall be
mounted in a sealed subenclosure. The HF driver shall be
loaded on constant directivity horn with a nominal coverage
pattern of 90 (h) x 45
°
(v). An internal passive filter net-
work shall provide fourth order acoustical crossover and sys-
tem equalization.
System frequency response shall vary no more than
±
3 dB
from 45 Hz to 17 kHz measured on axis. In passive mode,
the loudspeaker shall produce a Sound Pressure Level (SPL)
of 101 dB SPL on axis at 1 meter with a power input of 1
Watt, and shall be capable of producing a peak output of
134.8 SPL on axis at 1 meter. The loudspeaker shall handle
600 Watts of amplifier power (AES Standard) and shall have
a nominal impedance of 4 Ohms.
In biamped mode, the passive mid/high section shall meet
all passive mode performance criteria. The LF section in
biamped mode shall produce a Sound Pressure Level (SPL) of
101 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 SPL
on axis at 1 meter. The LF section in biamped mode shall
handle 1000 Watts of amplifier power (AES Standard) and
shall have a nominal impedance of 4 Ohms.
The loudspeaker enclosure shall be rectangular 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 dual Neutrik NL4 Speakon.
The system shall include a switch allowing in to be operated
in biamp or passive Powering mode. Caster wheels and handles
shall be installed as well as two 3/8"-16 threaded mount-
ing/suspension points (on top). The front of the loudspeaker
shall be covered with a vinyl coated perforated steel grill.
The 3-way fullrange loudspeaker shall be the EAW model
FR253e.
