Ahuja SUH-25 Electrical, Amplifier, and Mounting Compatibility

The Ahuja SUH-25 low-impedance public address horn speaker is engineered for seamless integration into direct-drive PA systems, mobile broadcast setups, and industrial alert networks. Operating with a nominal electrical impedance of 8 ohms (8Ω), the unit interfaces directly with low-impedance commercial amplifiers, mobile PA booster units, and two-way announcement systems without requiring an internal line-matching transformer.

Amplifier Matching and Power Handling Compatibility

System integrators must pair the Ahuja SUH-25 with amplifier channels rated to drive an 8-ohm load safely. The driver is engineered to handle 25W RMS continuous power with a maximum rating of 38W Max. Voice coils precision-wound on a heat-conductive aluminium bobbin ensure rapid heat dissipation, allowing stable continuous duty during industrial paging cycles, vehicle announcements, and emergency siren broadcasts. Amplifiers with output ratings aligned to 25W–38W into 8 ohms provide optimal driver excursion and sound pressure performance (delivering 108 dB/1W/1m and up to 122 dB/25W/1m at 1 kHz across a 250 Hz to 10,000 Hz frequency response band).

Wiring and Cable Lead Interfacing

Electrical termination is achieved through the factory-fitted 0.6 m (2 ft) 2-core sheathed speaker cable. The pre-terminated cable enters the rear driver housing through an integrated, water-tight, and tug-proof cable gland. This configuration ensures compatibility with:

• Standard industrial junction boxes and outdoor weatherproof terminal enclosures.
• Direct splice and terminal block connections within 8-ohm PA circuit loops.
• Vehicle and mobile public address wiring looms operating from 12V/24V mobile low-impedance power amplifiers.
• Marine and boat announcement control units requiring secure, sealed cable entries.

Mechanical and Mounting Compatibility

The unit features a robust, heavy-duty metal mounting bracket that rotates through a complete 270-degree arc. This 270° adjustability facilitates secure mechanical fixing to horizontal, vertical, and angled surfaces, including:

• Flat wall surfaces, pillars, and structural steel beams in industrial facilities and warehouses.
• Outdoor lighting poles, perimeter masts, and security stanchions.
• Mobile vehicle rooftops, utility racks, public safety vehicles, and commercial boats.

Weighing 1.90 kg with horn mouth dimensions of 315 mm x 165 mm and a depth of 290 mm, the rectangular flare profile is optimized for tight vehicle profiles and directional acoustic projection across wide coverage areas.

Environmental and Regulatory Compliance

Built from UV-protected ABS plastic, the SUH-25 horn speaker provides IP66 ingress protection against high-pressure water jets and total dust ingress, ensuring compatibility with harsh outdoor, coastal, and industrial plant conditions. Furthermore, the unit complies with European Union standard EN 60065 under the Low Voltage Directive, ensuring adherence to industrial electrical safety regulations.
