Low-profile Ceiling Speaker with Low-end Extension AtlasIED’s GD87W ceiling speaker is a lightweight, low-profile solution for overhead audio. This speaker comes loaded with an 8-inch low frequency driver paired with a 3-inch coaxial high frequency driver, delivering an ear-pleasing sound throughout its 55Hz–15kHz frequency response. Installers will also appreciate the uniform 105-degree dispersion pattern, which helps cover a space with fewer speakers. AtlasIED also tells Sweetwater that the speaker features a high-efficiency 8-watt 70.7-volt transformer to minimize insertion loss. You also get primary taps for 1-, 2-, 4-, and 8-watt operation. The GD87W ships with a factory-installed 62-8-style CRS baffle with concealed speaker mounting studs.
