Abstract: Two unit direct-radiator loudspeakers may be constructed in many different ways. In order to determine some of the characteristics, a number of experimental designs were built and tested. As a result of these experiments, it appeared that the duo-cone loudspeaker, consisting of two coaxial, congruent, separately driven cones, possessed many constructional, theoretical, and experimental advantages. Consequently, a detailed theoretical and experimental investigation of the duo-cone loud-speaker was carried out to determine the optimum values for the constants of the system from the standpoint of the following characteristics: pressure response, directional pattern, distortion, and transient response. The results of these investigations are included.
