CSC Horn projectors are widely used in public address systems for large venues. These weatherproof outdoor speakers are perfect for placement in a backyard, under a ledge of the ceiling, pool areas, porches, parking lots and more. In spite of a restricted frequency response, it has a greater acoustic output, which is smooth and natural. The horn is designed to increase the overall efficiency of the driving elements. A flaring duct helps conduct the sound waves through air, improving the coupling efficiency between the driver and the air. The horn goes thought an acoustic transformer providing impedance matching.
