Loudspeaker (PZA)

8" coaxial ceiling speaker with 70.7V, 8W transformer, baffle and Hyfidrophobic™ treated coating

The DD87W-HC is a high-performance coaxial speaker package with identical performance specifications to the legendary AtlasIED C803A model. This similarity in sound quality ensures that existing C803A systems can be expanded with the new DD87W-HC without noticeable differences in sound or performance.

This coaxial speaker features a frequency response of 45 Hz - 19 kHz (nominal) and a wide, uniform 105° dispersion pattern (2 kHz octave band). The DD87W-HC combines a full-size 8" (203 mm) diameter low-frequency driver and a 3" (76 mm) high-frequency driver. The two sections are coupled by a built-in cross net. The woofer is 10 oz. (260 g) ceramic magnet; the tweeter is 2.35 oz. (67 g) ceramic magnet. The unit has an average sensitivity of 96 dB (1 W/1 m).

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

The DD87W-HC includes a factory-installed 62-8 style CRS baffle with hidden speaker mounting studs and includes screw mounting hardware. The baffle finish is a white epoxy powder coat and is completed with an application of AtlasIED's patented hydrophobic treatment that resists moisture, allowing the unit to be used in high humidity environments.
