The loudspeaker used in the SD72 is the next generation of Atlas high performance cone loudspeakers, very similar to the preceding C-Series loudspeakers. Similarity in 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 SD72.
Model SD72 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.
Model SD72 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 transformer with tap selections ranging from .25 to 5 watts.
The unit mounts a wide variety of AtlasIED round and square baffles and enclosures to meet functional and aesthetic application requirements.
