Compact 100W siren speaker for emergency vehicles

This slim-profile speaker delivers true 100-watt output through a neo-driver for reliable low-frequency sound. Its corrosion-resistant aluminum housing with black finish withstands harsh conditions. The unit mounts flush in grilles or between bumpers and hose trays on large apparatus.

11-ohm impedance matches any 100W PA siren amplifier

The speaker presents an 11-ohm load, making it compatible with standard 100-watt public-address siren amplifiers used in emergency fleets. No additional matching components are required for typical installations. This single electrical specification determines whether the unit suits a given siren system.

Suits fleets needing a lightweight.

Installers who value quick, cost-efficient fitting on fire apparatus or police vehicles will benefit from the 5.3-lb, 5.9-by-5.5-by-2-inch form factor. Buyers requiring a different impedance, higher power handling, or a non-flush mounting style should look at other models.
