Main Features of Directional Horn Speaker
- By implementing a perfect exponential horn, the sound quality is good and the output performance is very good. In other words, the sound is very large compared to the output.
- The horn loudspeakers are thick, contain vibration suppression functions, and are not swayed by high-power broadcasts, and their clarity (STI) is remarkably good.
- UV protection function : It does not corrode even in sunlight and has a long life.
- Flame retardant function : It is strong against fire.
