ARCHITECTURAL SPECIFICATIONS
The two-way full range loudspeaker systems shall incorpo-
rate 2x 5.25-in LF transducers and a 1-in exit compression
driver HF transducer.
The HF driver shall be loaded on a constant directivity horn
with a nominal coverage pattern of 120
°
(h) x 50
°
(v). The
LF drivers shall be mounted on separate angled baffles to
match the HF horn’s coverage angle. An internal passive fil-
ter network shall provide fourth order acoustical crossover
and system equalization.
System frequency response shall vary no more than
±
3 dB
from 100 Hz to 19 kHz measured on axis. The loudspeaker
shall produce a Sound Pressure Level (SPL) of 93 dB SPL on
axis at 1 meter with a power input of 1 Watt, and shall be
capable of producing a peak output of 122 SPL on axis at 1
meter. The loudspeaker shall handle 200 Watts of amplifier
power (AES Standard) and shall have a nominal impedance
of 4 Ohms.
The loudspeaker enclosure shall be rectangular in shape with
the exception of the rounded front baffle. It shall be con-
structed of 3/4-in medium density fiberboard (MDF) with
the exception of the baffle which shall be15mm thickness
void-free cross-grain-laminated Baltic birch plywood. The
enclosure shall employ extensive internal bracing. It shall
be finished in black catalyzed polyurethane. Input connec-
tors shall be 2-terminal barrier strip. A total of four 1/4"-20
threaded mounting/suspension points (1 each top, bottom
and sides) shall be provided. The front of the loudspeaker
shall be covered with a vinyl coated perforated steel grill.
