The Ahuja SUH-25MT is an industrial-grade, rectangular 100V public address horn speaker engineered for clear speech transmission, emergency paging, and voice alerting across harsh or sprawling operational environments. Combining an IP66 ingress protection rating, UV-protected ABS construction, and an integrated multi-tap 100V line matching transformer, it provides reliable acoustic output across diverse commercial and industrial system architectures.
Industrial Manufacturing Plants and Heavy Work Yards
In high-ambient-noise manufacturing bays, processing plants, and fabrication yards, audio clarity within the human vocal range is essential for operational and safety paging. The Ahuja SUH-25MT delivers a rated Sound Pressure Level (SPL) of 108 dB/1W/1m (up to 122 dB at its full 25W RMS rating) across a targeted frequency response band of 250 Hz to 10,000 Hz. The precision-wound voice coil on an aluminium bobbin incorporates dedicated heat dissipation fins, ensuring sustained thermal endurance during extended voice announcements or continuous alert cycles. Its robust IP66-sealed housing resists airborne dust, metal particulate, and direct water jets commonly encountered during facility washdowns.
Large-Scale Warehousing and 100V Distributed Lines
Sprawling logistics terminals, inventory warehouses, and distribution centers require long cable runs connecting multiple speakers to central amplifiers. The SUH-25MT features an integrated 100V line matching transformer designed specifically to mitigate line loss and voltage drops across extensive cable lengths. System integrators can balance sound coverage across high-ceiling aisles, loading bays, and dispatch offices using the rear-mounted rotary tap switch without dismantling the enclosure.
- 25W (400Ω) / 20W (500Ω): Ideal for noisy loading docks, container staging zones, and active forklift routes requiring maximum acoustic penetration.
- 15W (670Ω) / 10W (1kΩ): Balanced coverage for intermediate storage bays and wide logistics corridors.
- 5W (2kΩ): Optimized tap setting for lower-ceiling buffer zones and covered walkways to prevent acoustic over-saturation.
Outdoor Perimeter Security and Boundary Intercom
Rectangular horn geometry (315 mm x 165 mm with a 290 mm depth) provides directional sound dispersion, directing acoustic energy along security fences, gates, entry barriers, and facility perimeters rather than dispersing power inefficiently. The UV-stabilised ABS flare and back cover prevent structural degradation under intense sunlight, while external stainless steel stand mounting bolts resist corrosion from rain and humidity. Pre-fitted with a 0.6 m 2-core sheathed speaker cable exiting through a watertight, tug-proof cable gland, the unit integrates smoothly with outdoor junction boxes.
Mobile Public Safety and Utility Fleet Vehicles
Weighing 1.90 kg (2.1 kg gross packed weight), the SUH-25MT is suitable for roof-rack or bumper mounting on emergency response vehicles, municipal inspection fleets, and industrial patrol utility trucks. Its compliance with European Union standard EN 60065 verifies rigorous electrical safety, and the rugged ABS horn flare withstands road vibration and weather exposure during mobile public address operations.
