ARCHITECTURAL SPECIFICATIONS
The two-way full range loudspeaker systems shall incorpo-
rate a 15-in LF transducer and a 1-in exit compression HF
transducer.
The LF driver shall be mounted in a vented enclosure tuned
for optimum low frequency response. The HF driver shall be
loaded on a constant directivity horn with a nominal cover-
age 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 70 Hz to 17 kHz measured on axis. The loudspeaker
shall produce a Sound Pressure Level (SPL) of 98 dB SPL on
axis at 1 meter with a power input of 1 Watt, and shall be
capable of producing a peak output of 130.8 SPL on axis at
1 meter. The loudspeaker shall handle 480 Watts of amplifier
power (AES Standard) and shall have a nominal impedance
of 8 Ohms.
The loudspeaker enclosure shall be irregularly trapezoidal in
shape and shall have rubber footpads on two sides allowing
its baffle to be angled up 45° or 15°. 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 polyurethane. Input
connectors shall be dual Neutrik NL4 Speakon. Two 5/8"-18
threaded mounting/suspension points shall be provided on
top configured to accept an external Ultimate Brand
standmount adapter. A midrange frequency attenuating pres-
ence control shall be provided. The front of the loudspeaker
shall be covered with a vinyl coated perforated steel grill
backed with open cell foam to protect against dust.
The two-way full range loudspeaker shall be the EAW model
SM155e.
