Architect & Engineer Speciﬁcations

Loudspeaker shall be Atlas Sound Model AH99-8ST or approved equal.

The loudspeaker system shall be a horn-loaded, 2-way design with an 8"

inch polycone woofer.

The loudspeaker system shall include an 8", 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

(18 dB/octave) dividing network shall have a crossover frequency of 1.8

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 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 100 dB SPL (90 Hz – 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 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 70.7V transformer with 7.5, 15, 30, & 60

watts taps and a bypass 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: 21.88" (555.75 mm)

* EIA test spectrum is applied for eight hours.

(This procedure provides a rigorous test of both thermal and

mechanical failure modes.)
