The GD87 is a high-performance coaxial loudspeaker with performance specifications identical to the legendary AtlasIED Model C803A. This similarity in sonic quality ensures that existing C803A systems may be expanded with the new GD87 without any noticeable sonic or performance differences.
The high-quality, 16-watt Model GD87 utilizes a post-mounted tweeter, which adds strength to the assembly and provides an attractive appearance. This coaxial loudspeaker features a 45 Hz - 19 kHz (nominal) frequency response and a broad, uniform dispersion pattern of 105° (2 kHz octave band). The GD87 combines a full-size 8" (203 mm) dia., low-frequency reproducer and a 3" (76 mm) 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. (67 g) ceramic magnet. The unit has an average sensitivity of 96 dB (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 +1 dB from 50 Hz - 15 kHz. The primary taps are 1, 2, 4, and 8 watts.
