Abstract:
A manifold for delivering acoustic power to the throat end of a horn of a horn loudspeaker, said manifold comprisingan input end having at least one input port for receiving acoustic power from at least one acoustic driver, an output end for delivering acoustic power to the throat end of the horn, said output end having at least two aligned output ports, and an acoustic power waveguide associated with each of the aligned output ports and connecting said output ports to said at least one input port, such that acoustic power received by said input port is divided between said acoustic waveguides, and such that the acoustic power divided between said acoustic power waveguides is delivered to said aligned output ports to simulate a line array of acoustic power sources, the acoustic path lengths of said acoustic power waveguides from said at least one input port to said aligned output ports being relatively short in relation to the wavelength of the acoustic power passing through the manifold at the highest operating frequency range of the horn loudspeaker.
