Product Description

The C10AT72 is part of the AtlasIED C10A series of acoustically proven 8-inch in-ceiling speakers engineered for multi-purpose distributed audio systems. The dual cone design delivers full-range performance from 100Hz to 10kHz with a 105-degree wide dispersion pattern that provides even sound coverage across rooms of varying sizes. The 10 oz ceramic magnet provides reliable magnetic circuit performance, while the curvilinear treated paper cone reduces harmonic distortion for cleaner audio reproduction. A 1-inch diameter copper voice coil wound on a black anodized aluminum former dissipates heat efficiently during extended operation, supporting the 25-watt continuous power rating. The factory-installed LT-72 transformer supports 25V and 70V distributed audio systems with power taps at 0.25, 0.5, 1, 2, and 4 watts for precise load balancing on multi-speaker circuits. This pair is finished in black for installations requiring a dark ceiling appearance. The C10AT72 is UL Listed to UL1480A and UL2043, meeting fire safety requirements for plenum and general ceiling installations. Compatible with a wide range of AtlasIED round and square baffles, the C10A series allows specifiers to choose the enclosure type that best fits the acoustic and aesthetic requirements of the space. A 60-month warranty applies from the date of purchase.
