EX-900R – Ultra-Directional Loudspeaker
The Revoluce EX-900R Long-Range Acoustic Device (AHD/LRAD-type) is a next-generation, high-power acoustic communication system engineered for the demanding requirements of Indian defence, maritime security, industrial operations, and critical-infrastructure protection. Designed for ultra-clear voice transmission, high-intensity warning tones, and precision directional output, the EX-900R ensures reliable long-range communication even in high-noise, high-wind, and harsh coastal environments across India.
Powered by advanced straight-sound projection technology, the EX-900R delivers exceptional peak output, tight beam accuracy, and superior long-range intelligibility, making it highly effective for coastal surveillance, port and harbour security, offshore platforms, industrial safety alerts, wildlife and bird-deterrent operations, and large-area emergency broadcasting.
With India placing increasing emphasis on maritime security, border-protection infrastructure, disaster-management communication, and airport wildlife-control systems, the Revoluce EX-900R stands out as a reliable, professional-grade long-range acoustic solution trusted by government agencies, private operators, and system integrators seeking performance, durability, and non-lethal deterrence capability.
