New Permanent Magnet Public Address Loudspeaker
This paper describes the permanent magnet type of Duplex loudspeaker and its use in theater public address systems. Its efficiency and frequency response is shown. Special types of baffles for the sides of the stage and above the screen are described. Because of its high efficiency and wide angle of distribution and extreme frequency range along with its small physical size, it provides a 2-way horn system with many advantages over those in present use.
