ABSTRACT:
A method is provided for computing frequency responses of crossover filters for multi-way loudspeakers. The method prescribes driver coordinates for drivers in the multi-way loudspeaker, prescribes an attenuation function for the sound pressure level at a desired angle, computes the crossover frequencies using a point source model and computes the frequency responses in intervals defined by the crossover frequencies.
