The two-way full range loudspeaker systems shall incorpo-
rate 4x 5.25 LF transducers and 2x 1-in exit compression
driver HF transducers.
The HF drivers shall be loaded on dual constant directivity
horns with a combined nominal coverage pattern of 170°
(h) x 60° (v). The LF drivers shall be mounted on separate
angled baffles to match the HF horn’s coverage angle. 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 18 kHz measured on axis. The loudspeaker
shall produce a Sound Pressure Level (SPL) of 94 dB SPL on
axis at 1 meter with a power input of 1 Watt, and shall be
capable of producing a peak output of 125.4 SPL on axis at
1 meter. The loudspeaker shall handle 350 Watts of amplifier
power (AES Standard) and shall have a nominal impedance
of 8 Ohms.
The loudspeaker enclosure shall be irregular in shape, fea-
turing a low vertical profile and a wide horizontal arch. It
shall be constructed of 1/2-in 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.
A total of three 1/4"-20 Threaded Mounting Points (1 each
