AtlasIED C803A 8" Coaxial In-Ceiling Speaker 16W 8 Ohm

The AtlasIED C803A is an 8-inch coaxial in-ceiling loudspeaker built for commercial, industrial, and institutional audio systems where consistent, intelligible coverage is non-negotiable. System integrators and AV installers working in retail spaces, offices, houses of worship, schools, and healthcare facilities will find the C803A a dependable choice that meets UL1480A and UL2043 safety certifications required for plenum and life-safety applications.

The coaxial design pairs a full-size low-frequency reproducer with a 3-inch high-frequency driver coupled through a built-in crossover network, eliminating the need for external filtering and simplifying installation. The post-mounted tweeter is a structural asset as well as an aesthetic one, reinforcing the assembly where conventional mounting methods introduce weak points. The broad, uniform 120-degree dispersion pattern reduces the number of speakers needed to achieve even coverage across a room, directly impacting system cost and installation time.

With compatibility across a wide range of AtlasIED baffles and enclosures, the C803A integrates cleanly into new construction and retrofit projects alike. The specified optimum sealed enclosure volume gives installers a precise target for custom millwork or prefabricated enclosure selection, removing guesswork from the design phase. At 8 ohms with no step-down transformer required, the speaker connects directly to standard low-impedance amplifier outputs, keeping signal paths simple and losses minimal.
