AtlasIED C803AT87 8" Coaxial In-Ceiling Speaker With 70V Transformer

The AtlasIED C803AT87 is engineered for integrators and systems contractors specifying distributed audio in commercial, institutional, and industrial environments. The factory-installed 70.7V 8-watt line-matching transformer makes this speaker a direct fit for 70V distributed systems without requiring field modification, reducing installation time and potential wiring errors on large-zone projects.

The coaxial architecture pairs an 8-inch low-frequency driver with a 3-inch post-mounted tweeter coupled through a built-in crossover network. The post-mount tweeter design reinforces the assembly mechanically while delivering a cleaner aesthetic in finished ceiling applications — a meaningful advantage in hospitality, education, and corporate environments where appearance matters alongside performance. A 120-degree dispersion pattern supports even coverage across broad listening areas, reducing the number of speakers required to achieve uniform intelligibility.

With UL certification to UL1480A and UL2043, the C803AT87 meets the safety requirements for audio systems in air-handling spaces, satisfying common specification requirements for commercial construction. Compatible with a wide range of AtlasIED baffles and enclosures, it adapts readily to new construction or retrofit ceiling scenarios where enclosure selection is dictated by existing cavity depth.
