Horn loaded PA speakers are designed with unique features, particularly horns. Horns works as an acoustic transformer that blends and emits the sound from the driver to air. Furthermore, the structure has higher directivity which means sound can be focused in one area resulting in more concentration and intensity in that region. In theaters, horn loaded PA speakers are used to focus the sound towards specific audience seats so the viewers experience the best optimized sound quality. These speakers are also commonly used in public address systems for indoor areas like convention centers where the voice needs to travel over long distances but distortion has to be minimized.
