AB  - A family of asymmetric crossover filters is investigated that expands the established all-pass set. A general method of determining complementary crossover filters with an all-pass composite response is presented together with a method of reflecting the crossover asymmetry about the crossover region; a number of example filters is included. CAD techniques are used to verify the basic approach and a simple application to a satellite/subwoofer loudspeaker is described where asymmetry in the crossover frequency response and the resulting overlapping of the high-pass and low-pass responses is shown to improve the effectiveness of filter attenuation. However, because of asymmetry in the high-pass and low-pass phase responses and the resulting polar response irregularity in association with noncoincident drive units, the application regime for these alignments is restricted to low frequency.
