    DESCRIPTION

    The GD87W is a high performance coaxial speaker package with performance specifications identical to the legendary AtlasIED Model C803A. This similarity in sonic quality insures that existing C803A systems may be expanded with the new GD87W without any noticeable sonic or performance differences.

    This coaxial speaker features a 45Hz -19kHz (nominal) frequency response and a broad, uniform dispersion pattern of 105° (2kHz octave band). The GD87 combines a full-size 8" (203mm) dia., low-frequency reproducer and a 3" (76mm) high-frequency reproducer. The two sections are coupled via a built-in crossover network. The woofer has a 10oz. (260g) ceramic magnet; the tweeter has a 2.35 oz. (67g) ceramic magnet. The unit has an average sensitivity of 96dB (1W/1m).

    The speaker is matched with a high efficiency 8 watt 70.7V transformer with a maximum insertion loss of 0.6dB. This premium transformer is constructed of audio grade laminations and has a full range frequency response of +1dB from 50Hz - 15kHz. The primary taps are 1, 2, 4, and 8 watts.

    The GD87W includes a factory installed 62-8 style CRS baffle with concealed speaker mounting studs and includes screw mount hardware. The baffle finish is white powder coat epoxy.

    Speaker Placement Tool

    The AtlasIED Speaker Placement Tool is designed to make it easy to select the proper positioning of speakers in a given room. Choose your AtlasIED speaker and the transformer taps that you plan on using. Then input the room length, width, and ceiling height. Don’t forget to choose feet or meters as your unit of measure and the listener level. The results will tell you how many total speakers are required and how they need to be positioned to maximize the sound coverage in the space.
