Abstract
A loudspeaker horn has a conical section adapted to receive the driver assembly of a speaker system at the small cone end. An exponential section secured to the large cone end, concentrically with the cone longitudinal axis, flares outwardly to terminate in a square cross-section horn mouth. A raised lip secured around the periphery of the horn mouth diffracts sound symmetrically through a dispersion angle of about 120.degree. with a drop of about six decibels or less.
