ARCHITECTURAL SPECIFICATIONS
The two-way full range loudspeaker systems shall incorpo-
rate a 5.25-in LF transducer a 3/4-in HF transducer.
The LF driver shall be mounted in a vented enclosure tuned
for optimum low frequency response. The system shall have
a nominal coverage pattern of 120 (conical). An internal
passive filter network shall provide fourth order acoustical
crossover and system equalization. The drivers shall be mag-
netically shielded allowing the systems to be used in imme-
diate proximity to video monitors.
System frequency response shall vary no more than 3 dB
from 98 Hz to 20 kHz measured on axis. The loudspeaker
shall produce a Sound Pressure Level (SPL) of 89 dB SPL on
axis at 1 meter with a power input of 1 Watt, and shall be
capable of producing a peak output of 116.5 SPL on axis at
1 meter. The loudspeaker shall handle 140 Watts of amplifier
power (AES Standard) and shall have a nominal impedance
of 8 Ohms.
The loudspeaker enclosure shall be rectangular in shape and
shall be available in left/right mirror-imaged pairs. It shall
be constructed of 3/4-in medium density fiberboard (MDF)
and shall employ extensive internal bracing. It shall be fin-
ished in black catalyzed polyurethane. Input connectors shall
be 2-terminal barrier strip. A total of four 1/4"-20 threaded
mounting/suspension points (1 each top and bottom, 2 on
one side to accept Omnimount Series 25) 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
