Atlas IED AH94-8T-BSG Data Sheet
AH94-8T-BSG
8" 2-Way Stadium Horn System 90° x 40°
Applications
Atlas Sound model AH94-8T-BSG stadium horn is ideal for directional sound
distribution where full range reproduction, maximum intelligibility, and high
sound pressure levels are required. Applications include football stadiums,
sports arenas, baseball fields, convention centers, and auditoriums.
Weather resistant construction features of the AH94-8T-BSG include a
multiple screen configuration to prevent moisture from damaging
internal components.
A perforated aluminum screen covers the large horn mouth, a secondary
screen is in place forward of the high frequency driver, and a third tightly
perforated screen protects the 8" cast frame woofer.
Installation
A heavy-duty stainless steel "C" style mounting bracket is included with
the AH94-8T-BSG to allow easy mounting to most any flat surface. Three
drop forge eyebolts are also pre-installed (2-front of horn plus 1-rear for
"pull-up") for suspension mounting via load rated wire rope. (Use caution
when suspending any object overhead. Refer to installation manual for
more details).
The AH94-8T-BSG includes a weather resistant 7 pole terminal block
connector on the underside of the speaker for ease of hook-up. This
terminal block includes connection points for internal 70.7V transformer
with taps settings of 7.5, 15, 30, & 60 watts and 8Ω connection for
transformer bypass.

Architect & Engineer Specifications
Loudspeaker shall be Atlas Sound Model AH94-8T-BSG 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 (18dB/octave) dividing network shall have a crossover frequency of
1.8kHz. 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 2kHz 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, 2mm
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.
1
Sensitivity shall be 101dB SPL (90Hz – 15kHz in
measured at a distance of one meter on axis with a 1 watt input half
space (2.83V).
Overall frequency response shall be 90Hz – 15kHz (±5dB).
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 watt taps and a by-pass jumper direct coupled to the speaker for
nominal 8Ω operation. The system connections shall be protected from
the elements by a screw affixed weather resistant cover.
Dimensions shall be: Height: 20.05" (509.27mm)
Width: 19.66" (499.36mm)
Depth: 19.98" (501.14mm)
Weight: 63 lbs (28.6kg)
* EIA test spectrum is applied for eight hours.
