Architect & Engineer Specifications
Loudspeaker shall be Atlas Sound Model AH94-12ST or approved equal.
The loudspeaker system shall be a horn-loaded, 2-way design with a 12
inch paper cone and moisture resistant coating.
The loudspeaker system shall include a 12", 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 1.6 kHz. The dividing network shall include a poly switch 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 200 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
12" 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 103 dB SPL (80 Hz to 15 kHz in 1/3 octave bands)
measured at a distance of one meter on axis with a one watt input half
space (2.83V).
Overall frequency response shall be 80 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 nominal 8 Ω
operation. The system connections shall be protected from the elements
by a screw affixed weather resistant cover.
Dimensions shall be: Height: 24.68" (626.87 mm)
* EIA test spectrum is applied for eight hours.
(This procedure provides a rigorous test of both thermal and
mechanical failure modes.)
