  Atlas Sound siren loudspeaker 

HPG-100N

 is a reflex-type loudspeaker with a rectangular molded bell. It 

is rated at 100 watts RMS in electronic siren use. 

HPG-100N

 provides optimum sound level output of 120 dBA (mea-

sured at 1600 Hz, rated power, 3 meters on axis) and features a directed dispersion range of 80˚ x 105˚ (1 kHz octave 
band) to assure high-intensity acoustic penetration for electronic siren signals. Unit contains the patented Atlas Sound 

AS-100N

 compression driver 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 heavy-duty, one piece steel mounting bracket permits full-axis 
orientation of the loudspeaker 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 protec-
tion. Units are shipped complete with all components and installation data for field installation. Replacement head 
assembly (Model
