5" Wired Horn Speaker for Paging

This 5-inch wired horn speaker is built for indoor and outdoor paging systems. Its high-impact ABS plastic housing is completely weatherproof, allowing reliable operation in tough conditions. The unit suits installers who need a durable, fixed-location audio projector for voice announcements. It connects directly to compatible amplifiers via standard wired terminals.

Suited for voice paging.

The 200 to 15,000 Hz frequency response is tailored for speech intelligibility rather than full-range music reproduction. Buyers who want high-fidelity audio playback or deep bass should look at something else. The speaker requires a separate amplifier and fixed mounting, so it does not suit users needing a battery-powered or Bluetooth-enabled portable PA unit. Its 8 ohm impedance must match the amplifier output.

12 watt maximum input power

The 12 watt maximum input power rating determines the amplifier size this horn can safely handle. Exceeding this figure risks damage to the driver, while a significantly lower powered amplifier may not deliver sufficient volume for the intended coverage area. Match your amplifier's rated output to this 12 watt specification for correct operation. The 8 ohm impedance and 200 to 15,000 Hz response complete the key electrical parameters.

Questions about this item

How is the 5.25" horn speaker mounted and what step is often missed?

Secure the base using its 2.75" diameter mounting holes on a rigid surface; the step often missed is sealing the screw heads with outdoor-grade silicone to keep moisture out of the ABS housing.

What maintenance will the 8-ohm horn speaker need over time?

Inspect the wiring terminals and cone surround annually for corrosion or UV cracking; clean the horn mouth with mild soap and water, and re-torque the mounting bolts if vibration loosens them.

What limit appears first when the 12-watt speaker runs continuously at high volume?

The 12-watt maximum input power is the first limit; sustained operation near that level will cause the voice coil to overheat and trigger thermal compression before any mechanical failure occurs.
