SIRIN 450XL is a powerful long range acoustic device reliably ensuring communication over a 1700 m distance. It efficiently transmits voice commands at up to 150dB and can be as well used to deter hostile violators. Extremely high-power sound waves turn SIRIN 450XL into a sonic cannon sufficient to produce a loud, irritating noise powerful enough to hold the violators back or even incapacitate them.
