The speaker used in the SD72 is the next generation of Atlas high performance cone loudspeakers, very similar to the preceding C-Series speakers. 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" (205 mm) loudspeaker with a 10 oz. (260 g) 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.
The SD72 operates within a frequency response range of 45 Hz to 19 kHz (nominal) with a sensitivity of 97 dB 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.

Constant Voltage (70-Volt) Audio SystemsAudio distribution systems, especially those commonly used in department stores, warehouses, restaurants, etc., require that many loudspeakers be driven from a single audio amplifier over long runs of speaker wire. The "constant voltage" or "high impedance distribution" audio systems can be complex to understand at first, however, provides many advantages. Learn how to design your own 70-volt or 25-volt loudspeaker system.
