Buying Guide: Key Considerations For Public Address Horn Speakers
- Power vs. coverage: Higher wattage generally means broader sound coverage. Match wattage to your space size and audience distance.
- System compatibility: Decide between 70V/100V transformer systems and low-impedance setups. 70V/100V systems simplify wiring for large areas, while 8-ohm low-impedance units can provide clearer sound at shorter distances.
- Outdoor durability: Look for weather-resistant housings, vibration resistance, and secure mounting options for outdoor use.
- Tone options and sirens: If you need multiple alert tones or sirens, consider models with built-in siren functionality or easy external integration.
- Input versatility: A model with a handheld mic and PA controls offers flexibility for live events and emergency instructions.
- Installation and mounting: Check horn size, mounting brackets, and compatibility with existing 12V or mains-powered systems.
- Regulatory considerations: Verify that siren sounds or PA tones comply with local regulations to avoid legal issues.
