AH94-15-BSG

15" 2-way Stadium Horn System 90° x 40°

AH94-15-BSG

Features

• Efficiency rating of 102.5dB (1 W/1 M)

• 250 watts power handling

• Maximum output of 126.5dB (Rated Power @ 1 M)

• Constant directivity design offers controlled coverage of
90˚ H by 40˚V (2kHz octave band)

• Excellent low frequency response provides bass you can feel

• Driver complement includes a 15" cast frame woofer with a
concentrically mounted 1" exit compression driver coupled to a
90˚ H x 40˚V HF horn

• Full range frequency response of 75Hz – 14.5kHz (±5dB)

• Easy, weather resistant connection via a 4-pole terminal block
connector

• 8Ω nominal system impedance

• Heavy duty stainless steel mounting bracket (included) allows for
easy installation to almost any flat surface

• Three forged eyebolts also included for suspended installation

Applications

Atlas Sound model AH94-15-BSG stadium horn is ideal for shorter
throw and wide coverage 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 AH94-15-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 15"
cast frame woofer.

Installation

A heavy-duty stainless steel "C" style mounting bracket is included with
the AH94-15-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 aircraft cable. (Use
caution when suspending any object overhead. Refer to the installation
manual for more details).

The AH94-15-BSG includes a 4 pole terminal block, weather resistant
connector on the underside of the device for easy hook-up and daisy
chain wiring to other AH94-15-BSG. If 70.7/100V operation is required,
the optional Atlas Sound AF140 autoformer may be used. NOTE: Due to the
full range operation capabilities of the AH94-15-BSG 70.7/100V operation
is possible, but discouraged. Better frequency response and amplifier
dampening factor can be realized by using large gauge (#10 to #12) home
runs and series/parallel hook-up wiring at the head end location with direct
coupled, low impedance amplifiers. Generally speaking, this improvement
of frequency response and amplifier dampening factor is worth the sacrifice
of line loss over distance - especially if transformer insertion loss at the
loudspeaker location is considered.
