AtlasIED GD87 Series 8-Inch Coaxial In-Ceiling Speaker with Transformer, Baffle and Hardware Kit Option Available

The AtlasIED GD87 and GD87W are high-performance 8″ coaxial in-ceiling speakers engineered for professional commercial installations. These models match the sonic profile of the legacy C803A speaker, making them ideal for system expansions where uniform sound is essential.

Each speaker features a durable post-mounted 3″ tweeter paired with a treated paper 8″ woofer. With wide 105° dispersion and 96 dB sensitivity, the GD87 series provides excellent clarity for paging, background music, and general-purpose applications in schools, offices, and retail spaces.
