Abstract
A loudspeaker system having the ability to uniformly direct high-frequency as well as low-frequency sound hemispherically is described. The acoustical centers of a low-frequency and a high-frequency driver are aligned in space to provide a common source of sound to be directed through a common sound-guiding structure. The high-frequency sound is guided by the formation of an acoustical horn between the spherical mounting structure of the low-frequency driver and the reflector generally employed in reflecting and diffracting low-frequency sounds. One side of the acoustical horn has an acoustic path length smaller than the other, forcing sound to further diffract upon passage from the horn.
