The AH Series Stadium Loudspeakers offer the most often requested
coverage patterns while providing excellent intelligibility for the
most challenging environments including large auditoriums &
sport fields. With a complete family of 8", 12", and 15" 2-way
systems, designers and specifiers can select models for
whatever SPL is required with the peace of mind that all units will
provide outstanding pattern control.
90° H X 90° V models (8" and 12" models only) are suggested for
shorter loudspeaker to listener distances and/or wider coverage
requirements such as bleacher seating where the speaker may be
in close proximity to the crowd.
65° H X 65° V (8", 12" and 15" models) square coverage pattern
models are perfect for down-firing applications including convention
centers.
90° H X 40° V patterns (8", 12" and 15" models) work well when longer
speaker to listener distances require a tighter vertical coverage pattern.
15" AH series models offer an even slightly tighter pattern of 50° H X 40° V. This device is often mounted atop
football field press boxes with the device aimed at the visitor side in conjunction with wider coverage pattern
models to cover the home side bleachers.
Common Design Features
Multiple stainless steel mesh screens protect internal drivers
from weather and pest damage. A primary rodent screen provides
protection for all components, a secondary screen resides
between the high frequency horn and the driver, and a third
perforated screen protects the woofer.
Heavy-duty stainless steel mounting brackets are included with
all models and three dropforge eyebolts are also included for
overhead suspension (use only load-rated & approved hardware).
For light pole mounting Atlas Sound also distributes matching
mounting accessories from Allen Products. (see back)
15" models AH9040S, AH6565S and AH5040S feature impressive,
full range sound reproduction via a high excursion low frequency
woofer and a concentrically mounted 1" exit compression driver.
A well-designed, highly efficient internal passive crossover network
ensures proper transition between the two drivers, which collectively provide
frequency response from 75 Hz – 14.5 kHz (±5 dB).
With an efficiency rating in excess of 102 dB (1 W / 1 M), the 15" AH Series is a perfect
choice for high-energy music playback at sporting events and extended range speech reinforcement for large
venue emergency notification. The 8 Ω rating allows maximum low frequency response and is a good match
with Atlas Sound model CP700 amplifier. If transformer operation is required for long runs of smaller gauge
cable please contact tech support for proper configuration and
use of model AF140 auto-former. Termination is via rear mounted
terminal block with a Plexiglas cover for weather resistance.
The 8" & 12" 2-way models are perfect for applications where
space considerations will not allow installation of the larger 15"
2-way models. All 8" & 12" models include a 60 watt, 70.7V /
100V internal transformer which is accessed via terminal block
connector sealed by a weather resistant cover. Transformer may
also be bypassed for direct coupled 8 Ω operation.
12" AH models feature a version of the popular 12CXT60
compression driver coaxial loudspeaker.
8" 2-way AH models feature a version of the popular 8CXT60
compression driver coaxial loudspeaker.
