ARCHITECTURAL SPECIFICATIONS
The two-way full range loudspeaker systems shall incorpo-
rate 2x 8-in LF transducers and a 1-in exit/44mm Voice Coil
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 60
°
(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 92 dB SPL on
axis at 1 meter with a power input of 1 Watt, and shall be
capable of producing a peak output of 125.8 SPL on axis at
1 meter. The loudspeaker shall handle 600 Watts of amplifier
power (AES Standard) and shall have a nominal impedance
of 8 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 wear-resistant tex-
tured black paint. Input connectors shall be 1x 2-terminal
barrier strip and 2x Neutrik NL4 Speakons. A total of ten 3/
8"-16 threaded mounting points (2 each top and bottom, 3
per side) shall be provided. The front of the loudspeaker
shall be covered with a powder coated perforated steel grill.
The two-way full range loudspeaker shall be the EAW model
UB82e.
