    • Individually packaged for stocking & ordering convenience
    Use Atlas Sound 8" (203mm) dia., multi-purpose, coaxial loudspeaker
    Model GD87W for voice transmission, music and signal reproduction in
    high-quality commercial, industrial and institutional applications.
    The speaker used in the GD87W is the next generation of Atlas Sound
    high performance cone loudspeakers, very similar to the preceding
    C-Series speakers. The similarity in the sonic qualities ensures that
    contractors and designers who have worked with the Atlas Sound C803A
    Series in the past will know exactly what to expect when they use the
    High-quality, 25W Model GD87W utilizes a post mounted tweeter which
    adds strength to the assembly and provides an attractive appearance.
    This coaxial loudspeaker features a 55Hz-15kHz ±5dB frequency
    response and a broad, uniform dispersion pattern of 90° @ 2kHz. Such
    provisions allow for highly intelligible sound reproduction and better
    distribution for high-quality sound systems. The GD87W 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 10 oz. (260g) ceramic magnet; the
    tweeter has a 2.35oz. (67g) ceramic magnet.
    The unit has an average sensitivity of 96dB (1W/1M). The loudspeaker 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 CRS baffle with concealed loudspeaker
    mounting studs and includes screw mount hardware. The baffle finish is
    white powder coat epoxy.
    Unit shall be Atlas Sound 8" diameter. loudspeaker/transformer/
