Abstract
A loudspeaker horn for use with an acoustical driver has a rectangular throat opening with a long dimension relative to the wavelength of the sound pressure waves generated within the high frequency range of the horn. A relatively short pre-load chamber corrects the phase of the sound pressure waves over the long dimension of the throat opening. The pre-load chamber provides control over the directivity of the horn and provides a uniform frequency response with minimal distortion.
