SPECO TECHNOLOGIES

SPECO TECHNOLOGIES 25 WATT ALUMINUM PA HORN surveillance accessory

SKU CH-TNAB-ZGV8K

25 W weatherproof aluminium horn speaker rated at 110 dB sensitivity for outdoor PA use

  • Clear voice projection with 110 dB sensitivity
  • Reliable 15 W RMS output for continuous use
  • Weatherproof aluminium enclosure suits outdoor installs
  • Light 2.5 lb design eases mounting
  • Broad 200 Hz to 15 kHz frequency response

25 Watt Aluminium PA Horn

This Speco Technologies horn speaker is a surveillance accessory designed for public-address paging in outdoor or semi-outdoor areas. Its aluminium enclosure and weatherproof construction suit installers who need durable voice projection for campus, industrial or perimeter zones.

Sustained Output and Coverage

The driver handles 15 watts RMS continuously and accepts peaks up to 25 watts without thermal compression. An 8 ohm impedance and 110 dB sensitivity keep output stable over long announcements, while the 200 Hz to 15 kHz response preserves speech intelligibility at distance.

Upgrade Path and Fit

The unit replaces lower-powered paging horns that distort at modest volumes or lack weather sealing. The step up is justified when existing speakers cannot maintain clarity across the required coverage area or fail in exposed mounting locations.

  • Reliable 15 W RMS output for continuous use
  • Weatherproof aluminium enclosure suits outdoor installs
  • Light 2.5 lb design eases mounting

Questions about this item

How loud does the 110 dB horn get when driven at its 25 W maximum all day?

At full 25 W input the horn reaches 110 dB sensitivity; continuous operation at that level will produce significant heat in the voice coil and the aluminium enclosure will become warm to the touch.

What amplifier output impedance must I already have to connect this 8 ohm speaker?

The horn presents an 8 ohm load, so your amplifier must be rated for 8 ohm operation and able to deliver up to 25 W RMS without clipping.

Will the 200 Hz low-frequency limit match the response of older paging horns I want to keep in the same zone?

With a 200 Hz to 15 kHz range the horn reproduces voice clearly but lacks deep bass; older horns with a lower cutoff will sound fuller, so balance levels carefully when mixing them.
