The AtlasIED GD87 is built for installed audio professionals who need a reliable, high-performance 70V ceiling speaker that integrates cleanly into commercial distributed audio systems. Its coaxial design combines a full-size low-frequency driver with a post-mounted high-frequency reproducer coupled through a built-in crossover, making it a direct-fit expansion option for existing C803A installations without introducing audible mismatches in tone or output.
System integrators working in hospitality, retail, corporate, or house-of-worship environments will appreciate the broad 105° dispersion pattern, which supports consistent coverage across large ceiling grids without requiring additional fill speakers. The factory-installed 8-watt 70.7V transformer with primary taps at 1, 2, 4, and 8 watts gives installers flexible zone-level control without external transformer hardware, simplifying both initial installation and future system adjustments.
Safety compliance is built in from the factory — UL 1480 and UL 2043 listings satisfy the plenum-rated requirements common in commercial construction. With a 60-month warranty and individual packaging designed for efficient stocking, the GD87 is a practical choice for integrators managing multi-room installs or maintaining inventory for service calls on legacy AtlasIED systems.
