APPLICATION
The SD72 W is an aggressively priced, high quality speaker/baffle
transformer package suitable for most any paging or background
application including retail stores, restaurants, schools and other
institutional facilities.
GENERAL DESCRIPTION
The speaker used in the SD72 W 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
C-Series in the past will know exactly what to expect when they use
the SD72 W. Model SD72 W is a dual cone, 25 watt 8" (205mm)
loudspeaker with a 10oz. (260g) ceramic magnet. It includes a
curvelinear, treated paper cone for lower harmonic distortion. The
loudspeaker is also equipped with a full 1" diameter copper voice coil
with a black anodized aluminum former for better power dissipation.
Model SD72 W operates within a frequency response range of 45Hz-
19kHz (nominal) with a sensitivity of 97dB and a dispersion angle of
105°. Package includes factory installed 25/70.7V line matching trans-
former with tap selections ranging from .25 to 5 watts. The SD72 W
includes a factory installed CRS baffle with concealed loudspeaker
mounting studs and includes screw mount hardware. The SD72W
baffle features standard mounting holes to accommodate the majority
of Atlas Sound 8" tile bridges, mounting rings and enclosures. When
specifying mounting hardware be advised that the dimensions of the
SD72W baffle match the Atlas Sound Model 62-8. The baffle finish is
white powder coat epoxy.
