Model HPG-370GA provides optimum sound level output of 120dB (measured at 1600 Hz, rated power, 3 meters on axis) and features a directed dispersion range of 80H° x 105V° (1 kHz octave band) to assure high-intensity acoustic genetration for electronic siren signals.
Unit contains the patented AtlasIED SD-370A compression driver (U.S. Patent #7,760,501) complete with a non-fatiguing, self-aligning sound chamber assembly. These drivers have earned acceptance as the quality and performance standard for 100-watt electronic signal systems in police, fire, ambulance, and utility vehicles throughout the world.
A patented, heavy-duty, one piece steel mounting bracket (U.S. patent #394,660) permits full-axis orientation of the speaker for preferred sound-projection directivity. The projector assembly is manufactured of plastic and finished in black. The driver is finished in black baked epoxy for optimum durability and corrosion protection.
