High Powered Speaker Station

Superior Outdoor Intelligibility and Acoustic Coverage


The worlds most powerful giant voice mass notification system

Our most powerful siren, the HPSS provides exceptional voice clarity for outdoor mass notification applications where intelligibility of pre-recorded voice messages and live Public Address (PA) is critically important. The HPSS provides up to 3200 watts of continuous audio output. HPSS come in 1600 watt version as well. The system is also capable of driving strobe lights and LED message signs for visual alerting in areas with high ambient noise levels. The HPSS also offers flexible power solutions — seamlessly integrating with solar panels and a wide range of additional sources. The power and reliability of the siren station has made it the go to solution for military siren systems.
