Horn speakers are a type of loudspeaker that uses a horn-shaped enclosure to amplify and project sound. Horn speakers are often used in commercial and industrial settings where high sound levels and long-range projection are required.

There are some common uses for horn speakers:

Public address systems: Used to broadcast announcements, emergency alerts, or other important information in large outdoor or indoor spaces.

Outdoor events: They are designed to project sound over large areas and can provide high-quality audio even in open, outdoor spaces.

Paging systems: The directional nature of horn speakers allows them to project sound above the ambient noise level.

Mass notification systems: Horn speakers are often used in mass notification systems, which are used to broadcast emergency alerts and evacuation instructions in large facilities such as hospitals, schools, and government buildings.

Public transportation: The high volume and long-range projection of horn speakers make them ideal for public transportation systems such as trains and buses to make announcements and provide information to passengers.
