Horn Speaker uses an acoustic horn to increase the overall efficiency of the driver unit. The main advantage of horn loudspeakers is they are more efficient; they can typically produce 10 times (10 dB) more sound power than a cone speaker from a given amplifier output. Therefore horns are widely used in public address systems, megaphones, and sound systems for large venues like theaters, auditoriums, and sports stadiums.
DSPPA horn speakers cover a large scale of power outputs from 2W to 1000W. They are made of different materials and different shapes. Most of DSPPA horn speakers are designed waterproof for outdoor use.
