ARCHITECTURAL SPECIFICATIONS
The two-way full range loudspeaker systems shall incorporate 2x 8-in LF 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 HF driver shall be
loaded on a constant directivity horn with a nominal cover-
age pattern of 90° (h) x 70° (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 62 Hz to 20 kHz measured on axis. The loudspeaker
shall produce a Sound Pressure Level (SPL) of 95 dB SPL on
axis at 1 meter with a power input of 1 Watt, and shall be
capable of producing a peak output of 127 SPL on axis at 1
meter. The loudspeaker shall handle 400 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-grainlaminated Baltic birch plywood and shall employ extensive
internal bracing. It shall be finished in black catalyzed polyurethane. Input connectors shall be 2-terminal barrier strip
and dual Neutrik NL4 Speakon. A total of ten 3/8"-16 threaded
mounting/suspension points (2 each top and bottom, 3 per
side) shall be provided. The front of the loudspeaker shall be
covered with a vinyl coated perforated steel grill.
The two-way full range loudspeaker shall be the EAW model
UB82.
