A Subtractive Implementation of Linkwitz: Riley Crossover Design

Document Thumbnail

With the exception of the state variable implementation of Bohn, active crossover implementation of Linkwitz-Riley crossovers has been by cascading of multiple-feedback or Sallen and Key Butterworth filters. In 1983, Lipschitz and Vanderkooy showed that the Linkwitz-Riley filters were particular cases of a family of crossovers characterized by having their high- and low- pass responses in phase at all frequencies. This paper demonstrates practical active implementations of the subtractive approach for the second and fourth order cases. Advantages and disadvantages of this topology are discussed.
