Abstract
This paper gives a description of a new 2-way loudspeaker for theaters. New permanent magnet low-frequency and high-frequency units having replaceable diaphragms are described. These units are combined in a horn system having the following advantages: A higher efficiency, extended frequency range, permanent magnet units providing higher air gap flux densities, elimination of backstage radiation from the diaphragms, better transient response, and an improved over-all presence.
