ARCHITECTURAL SPECIFICATIONS

The two-way full range loudspeaker systems shall incorpo-

rate 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-grain-

laminated Baltic birch plywood and shall employ extensive

internal bracing. It shall be finished in black catalyzed poly-

urethane. 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.
