Design of digital linear-phase FIR crossover systems for loudspeakers by the method of vector space projections

A new technique for designing digital linear-phase FIR crossover systems for loudspeakers is proposed. The approach is based on the principle of vector space projections. We describe the constraint sets and their projections that capture the properties of the desired crossover filters. The proposed approach is capable of designing crossover networks for multiple band-splitting as well as for equalization. Designs that demonstrate the advantages and flexibility of this method are furnished
