ARCHITECTURAL SPECIFICATIONS
The two-way full range loudspeaker systems shall incorpo-
rate 2x 6.5-in LF transducers and a 1-in exit compression
driver HF transducer.
The HF driver shall be loaded on an axis-symmetrical wave
guide plate with a nominal coverage pattern of 100
°
(h) x
80
°
(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 85 Hz to 18 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 125.6 SPL on axis at
1 meter. The loudspeaker shall handle 460 Watts of amplifier
power (AES Standard) and shall have a nominal impedance
of 8 Ohms.
The loudspeaker enclosure shall be trapezoidal 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. The following mounting/sus-
pension shall be provided: two 1/4"-20 threaded mounting
points (1 each top and bottom); four 1/4"-20 threaded
mounting points on back to attach an Omnimount Series
100; two 5/16"-18 threaded mounting points (bottom) for
external Ultimate Brand standmount adapter. The front of
the loudspeaker shall be covered with a vinyl coated perfo-
rated steel grill backed with open cell foam to protect against
dust.
The two-way full range loudspeaker shall be the EAW model
JF80.
