- Abstract
- This paper describes a two-way loudspeaker system having an extended frequency range and exceptionally uniform distribution. These characteristics, which effectively meet the requirements for the presentation of stereophonic sound in motion-picture theaters, are obtained by the use of an acoustic lens. Spherical and elliptical lens elements accommodate the distribution pattern to variously shaped auditoria. Design features of the low-frequency horn provide a clean response which is essentially free from resonance.
