EX-900R2 – Advanced Ultra-Directional Acoustic Hailing Device

The Revoluce EX-900R2 Long-Range Acoustic Device (AHD/LRAD-type) is an upgraded, next-generation acoustic communication system engineered for demanding defence, marine, industrial, border-security, disaster-management, and critical-infrastructure missions. Designed for ultra-clear voice projection, powerful warning tones, and extended long-distance directional output, the EX-900R2 delivers dependable communication even in high-noise, high-wind, and extreme operating environments.

Using advanced straight-sound projection technology, the EX-900R2 provides higher peak output, improved intelligibility, and a tighter, more precise beam pattern—making it ideal for Indian defence agencies, coastal-security units, port authorities, offshore platforms, industrial safety teams, and emergency-response organisations that require accurate long-range communication.

With increasing focus on maritime security, border protection, smart-port operations, and large-scale disaster-response systems, the Revoluce EX-900R2 stands out as a high-performance long-range acoustic solution for government bodies, private operators, system integrators, and security forces looking for professional-grade non-lethal communication and deterrence capability.
