It’s compatible with 100–200 watt siren systems and is designed to work in tandem with a siren controller.

Buying Guide: Key Considerations For Car Horn Speakers
- Power and impedance: Higher wattage and lower impedance generally yield louder output, but may require more robust wiring and power handling. Ensure your vehicle’s electrical system can support the chosen speaker.
- Compatibility: Some horns require a compatible siren or control system. Verify whether the unit is standalone or must be paired with a siren controller.
- Environment: Outdoor and weatherproof ratings (IP66 or higher) are important for outdoor use or vehicles exposed to rain and dust.
- Mounting and space: Consider the available mounting space on the vehicle and the ease of wiring. Some units include mounting brackets; others require custom installation.
- Sound profile: For public-address tasks, focus on clear midrange and intelligibility. For attention-grabbing alarms, dB output and frequency range matter more.
- Use case: Choose a solution that matches your scenario—emergency communication, fleet alerts, or general vehicle announcements.
- Maintenance: Select models with durable housings and corrosion resistance if you operate in harsh environments or humid climates.
