Architect & Engineer Specifications
Loudspeaker shall be Atlas Sound Model AH94-8ST or approved equal.
The loudspeaker system shall be a horn-loaded, 2-way design with an 8”
polycone woofer.
The loudspeaker system shall include an 8”, horn loaded, cast frame
woofer and an integral, concentrically mounted 1” exit compression
driver coupled to a constant directivity high frequency horn. The three
pole (18 dB/octave) dividing network shall have a crossover frequency
of 1.8 kHz. The dividing network shall include a polyswitch protection
circuit for the high-frequency component.
The loudspeaker system shall be capable of providing a sound dispersion
angle of 90˚ horizontal by 40˚ vertical in the 2 kHz octave band.
Rated power shall be 100 watts RMS based on EIA Standard RS-426B.*
Enclosure shall be UV-resistant low pressure injection molded fiberglass
and shall include a 3 stage multiple mesh filter system for weather and
rodent resistance: to include a 20-gauge perforated aluminum screen on
front mouth assembly, a 100 x 100 weave stainless steel mesh between
HF horn and HF driver and a 100 x 100 weave stainless steel mesh over
8” woofer. The loudspeaker shall include a stamped and formed, 2 mm
stainless steel powder coated mounting bracket assembly for surface
mounting and three M8 drop forged eyebolts for suspension mounting
two at the front and one at the rear to allow the speaker system to be
suspended and aimed using rated wire rope.
Sensitivity shall be 101 dB SPL (90 Hz – 15 kHz in
1
⁄3 octave bands) mea-
sured at a distance of one meter on axis with a 1 watt input half space
(2.83V).
Overall frequency response shall be 90 Hz – 15 kHz (±5 dB).
The input section located on the bottom rear of the loudspeaker shall be
via 7 position screw down terminal strip internally configured to allow
input to an internally mounted 70.7 V transformer with 7.5, 15, 30, & 60
watt taps and a by-pass jumper direct coupled to the speaker for nomi
-
nal 8
Ω operation. The system connections shall be protected from the
elements by a screw affixed weather resistant cover.
Dimensions shall be: Height: 20.05” (509.27 mm)
Width: 19.66” (499.36 mm)
Depth: 19.98” (501.14 mm)
Weight: 100 lbs (45.36 kg)
* EIA test spectrum is applied for eight hours.
