Horn-Shaped Speakers


Style A	Style B

The horn-shaped design focuses the sound projection toward listeners.

Note: For speakers with several wattage options, the higher the watts, the louder your speaker will be. If you're connecting several speakers to one amplifier, the total watts of all speakers should not exceed the maximum wattage of the amplifier.

Dual Horn-Shaped Speakers

Focused through a dual horn-shaped design, these speakers project sound in two directions for broad coverage. Made of epoxy-coated aluminum, they withstand outdoor weather without corroding. They operate on a 70V line, so they integrate into distributed commercial sound systems. Use them in warehouses, parking structures, and other large facilities. The adjustable volume control lets you balance output across zones without returning to the amplifier. A mounting bracket is included for ceiling, I-beam, or wall installation.

Hazardous Location Horn-Shaped Speakers

These speakers are rated for environments where hazardous material is present. The horn-shaped design focuses the sound projection toward listeners. Speakers are NEMA 4X rated for protection from corrosion and washdowns.

Hazardous environmental ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it is rated for your environment.

I-Beam Mount Speakers

Bring clear audio to warehouses, factories, and other open structures where wall or ceiling mounting isn't practical. These speakers mount directly to I-beams using the included C-clamps. An epoxy-coated steel housing resists corrosion in humid or dusty industrial environments. Each speaker offers several wattage options with an adjustable volume control for fine-tuning output to your space. When connecting several speakers to one amplifier, the total watts of all speakers should not exceed the amplifier's maximum wattage.

Fire Alarm Speakers

When a fire breaks out, these speakers broadcast instructions. Connect them to your fire detection system and use your control panel to program the message. These speakers help you comply with NFPA 72 standards for fire alarm systems.

All speakers must be mounted to an outlet box: use an existing box in your facility, add an outlet box (sold separately), or choose a speaker that includes an outlet box.
