APPLICATIONS
Use Atlas Sound 8" (203mm) dia., multi-purpose, coaxial loudspeaker
Model GD87W for voice transmission, music and signal reproduction
in high-quality commercial, industrial and institutional applications.
GENERAL DESCRIPTION
The speaker used in the GD87W is the next generation of Atlas high
performance cone loudspeakers, very similar to the preceding
C-Series speakers. The similarity in the sonic qualities ensures that
contractors and designers who have worked with the Atlas Sound
C803A Series in the past will know exactly what to expect when they
use the GD87W.
High-quality, 25 watt Model GD87W utilizes a post mounted tweeter
which adds strength to the assembly and provides an attractive
appearance. This coaxial loudspeaker features a 55Hz-15kHz ?5dB
frequency response and a broad, uniform dispersion pattern of 90? @
2kHz. Such provisions allow for highly intelligible sound reproduction
and better distribution for high-quality sound systems. The GD87W
combines a full-size 8" (203mm) dia. low-frequency reproducer and a
3" (76mm) high-frequency reproducer. The two sections are coupled
via a built-in crossover network. The woofer has a 10oz. (260g)
ceramic magnet; the tweeter has a 2.35oz. (67g) ceramic magnet.
The unit has an average sensitivity of 96dB (1W/1M). The loudspeaker
is matched with a high efficiency 8 watt 70.7V transformer with a maximum
insertion loss of 0.6dB. This premium transformer is constructed
of audio grade laminations and has a full range frequency response of
+1dB from 50Hz-15KHz. The primary taps are 1, 2, 4, and 8 watts.
The GD87W includes a factory installed CRS baffle with concealed
loudspeaker mounting studs and includes screw mount hardware. The
baffle finish is white powder coat epoxy

 Atlas SBMSBeam Mount Speaker
FEATURES
• Easy-to-install loudspeaker package includes provisions for fast clamp-mount installation
to I-beams and girders
• Package includes an 8" dual-cone loudspeaker with a pre-mounted transformer, baffle
and enclosure equipped with clamp mounts
• Convenient lead wire extensions assure expedited field connection
• Durable white powder coat finish
GENERAL INFORMATION
The SBMS is ideal for "big box" retail stores whose special design calls for an open beam
ceiling. Since the goals are to get customers to pay attention to the announcements of
specials and the employees to respond to general paging—intelligibility is a top design
goal. The high efficiency of the specially designed 8" speaker included in the SBMS package
fills this requirement. Atlas gave the SBMS a square design, which blends in with the
overall aesthetic of an open beam ceiling.
The SBMS is infinitely flexible, complying with a variety of conduit requirements. Integral
knockouts facilitate 1.2" and 3.4" conduit where required by code while integral “romex” style
connector simplifies installation for applications where conduit is not required at all. The
SBMS also includes a 25V/70.7V internal transformer and is finished in neutral white
epoxy for simplified stocking and ordering.
