Architect & Engineer Specifications
Loudspeaker shall be Atlas Sound Model AH99-12ST 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 driv-
er coupled to a constant directivity high frequency horn. The three pole
(18dB/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 90˚ 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, steel reinforced, low pressure injection
molded fiberglass and shall include a 3 stage multiple mesh filter system
for weather and rodent resistance: to include a 20GA perforated alumi-
num screen on front mouth assembly, a 100x100 weave stainless steel
mesh between HF horn and HF driver and a 100x100 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 (3) 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 (80 Hz to 15 kHz in
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 to 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
watts 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: 25.68" (652.27 mm)
* EIA test spectrum is applied for eight hours.
(This procedure provides a rigorous test of both thermal and
mechanical failure modes.)
