Hello,

Here is an excerpt from the conclusion of the paper:

Optimum Loudspeaker Directional Patterns
JAES Volume 28 Number 11 pp. 787-794; November 1980
Author: Kates, James M.

"The result of our analysis is that loudspeakers should be more directional than conventional design practice.
For a listener located at a distance that is 0,5 to 2 times the loudspeaker separation, a cosine pattern (front lobe) will give good localization performance. For a listener closer to the loudspeakers, the loudspeaker beam-widths must be narrower to give accurate localization over the range of listener positions. Combined with the increase in directionality is a requirement that the loudspeakers be angled in toward the listening area so that the respective maxima of the directional patterns are aimed at the diametrically opposite ends of the listener locus".

Best regards from Paris,

Jean-Michel Le Cléac'h
