The loudspeaker used in theSD72Wis the next generation of Atlas high performance cone loudspeakers, very similar to the preceding C-Series loudspeakers. The similarity in the sonic qualities ensures that contractors and designers who have worked with the AtlasIED C-Series in the past will know exactly what to expect when they use the SD72W.

Model SD72W is a dual cone, 25 watt 8″ (205mm) loudspeaker with a 10oz. (260g) ceramic magnet. It includes a curvilinear, 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. Package includes factory installed 25/70.7V line matching transformer with tap selections ranging from .25 to 5 watts.

Model SD72W operates within a frequency response range of 45Hz – 19kHz (nominal) with a sensitivity of 97dB and a dispersion angle of 105.

The SD72W 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 AtlasIED 8″ tile bridges, mounting rings and enclosures. When specifying mounting hardware be advised that the dimensions of the SD72W baffle match the AtlasIED Model 62-8. The baffle finish is white powder coat epoxy.
