The AtlasIED SD72WV 8" Cone Speaker and 5W Transformer with Volume Control is the next generation of Atlas high-performance cone speakers, directly following the C Series. This particular model is a 25W, 8" loudspeaker and a 10oz ceramic magnet.
The harmonic distortion is greatly limited due to the curvelinear treated paper cone. To improve the power dissipation, a full 1" diameter copper voice coil with black anodized aluminum is incorporated.
This particular package includes a factory-installed 25/70.7V line-matching transformer with tap selections from 0.25 to 5W. The durable high-impact, injection molded plastic is obviously attractive and sturdy, but it also features a baffle, meant to blend effortlessly into contemporary architectural elements and match the AtlasIED Model 62-8.
