Abstract: An three-way audio system that uses directional arrays for radiating mid frequency acoustic energy and passive directional devices to radiate the high frequencies. The system includes a left channel, a right channel, and a center channel. A crossover network separates the left channel and the right channel into low frequency content, midrange frequency content, and high frequency content. An omnidirectional acoustical device radiates acoustic energy corresponding to the low frequency content of the combined left channel, right channel and center channel. A first directional array, comprising signal processing circuitry and more than one acoustic driver, radiates acoustic energy corresponding to the midrange content of one of the left channel and right channel signal so that more acoustic energy corresponding to the midrange content of one of the left channel signal and the right channel signal is radiated laterally than in other directions. A first passive directional device, radiates acoustic energy corresponding to the high frequency content of the one of the left channel and right channel signal so that more acoustic energy corresponding to the high frequency content of the one of the left channel signal and the right channel signal is radiated laterally than in other directions.

Abstract: An acoustic apparatus, including an acoustic driver, acoustically coupled to a pipe to radiate acoustic energy into the pipe. The pipe includes an elongated opening along at least a portion of the length of the pipe through which acoustic energy is radiated to the environment. The radiating is characterized by a volume velocity. The pipe and the opening are configured so that the volume velocity is substantially constant along the length of the pipe.
