AH66-8T-BSG
8" 2-Way Stadium Horn System 65° x 65°
Installation
A heavy-duty stainless steel "C" style mounting bracket is included with
the AH66-8T-BSG to allow easy mounting to most any flat surface. Three
drop forged 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 AH66-ST 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, and 60 watts and 8Ω connection for
transformer bypass.

Applications
Atlas Sound model AH66-8T-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 AH66-8T-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.

Architect & Engineer Specifications
Loudspeaker shall be Atlas Sound Model AH66-8T-BSG 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
driver coupled to a constant directivity high frequency horn. The three
pole (18dB/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 65˚ horizontal by 65˚ 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 100dB SPL (90Hz to 15kHz in
measured at a distance of one meter on axis with a one watt input half
space (2.83V).
Overall frequency response shall be 90Hz to 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.
