Why Choose the LMS-4000RXL?
✔ Ultra-Long-Range Performance
160 dB peak output paired with a precision ±10° beam gives extremely long reach up to 4.5 km, ideal for border patrol, naval forces, and large-area installations.
✔ Exceptional Directional Accuracy
A tighter beam width than standard LRAD-type systems ensures maximum clarity at long distances while reducing unwanted noise spill.
✔ Rugged, Weatherproof Construction
The IP67 enclosure withstands marine spray, saltwater, coastal humidity, desert dust, and extreme heat — perfect for India, UAE, Oman, and KSA operational conditions.
✔ High-Efficiency Power System
The 800 W RMS system supports powerful warnings, emergency alerts, and long-duration broadcasting without performance degradation.
✔ Mission-Ready Engineering
Optimised for defence forces, ports, airports, refineries, offshore rigs, and disaster-management agencies, the LMS-4000RXL provides reliable long-range acoustic communication and non-lethal deterrence in critical operations.
