AtlasIED C803AT47 8" In-Ceiling Coaxial Speaker with 4W 70V Transformer

The C803AT47 pairs an 8" woofer with a post-mounted 3" tweeter for a coaxial ceiling speaker built for background music and paging where wider high-frequency dispersion matters. A factory-installed 70.7V, 4-watt line-matching transformer drops it directly onto a distributed audio line.

UL 1480 and UL 2043 listings clear it for general signaling and plenum ceiling use, and its treated-paper cone construction targets the intelligibility and coverage commercial installers need.
