A method is presented for the evaluation of crossover filters in a multiway loudspeaker system. A number of analog filters, designed by hand or with CAD tools, are potentials for use in a loudspeaker system. These different filters are real-time simulated by a digital audio signal processor, which permits flexible and accurate switching between different crossover filters as needed in a listening test. The transformation of the analog filter to its digital equivalent and the implementation in a digital signal processor are discussed.
