It is shown that three-way all-pass crossover networks cannot be successfully derived from two-way all-pass networks if easily alignable passive ladder circuits are to be used. New transfer function triples are introduced which do allow the ladder implementation of three-way all-pass networks. Detailed circuits and alignment formulas are given to show how the new crossover networks may be passively realized.
