====== Horbach-Keele Crossover ====== {{:bilder_funktionen:gen_horbach_keele_crossover.png?nolink&}} **Description:** Creates a crossover network (XO files) similar to the Generate → Crossover function, but in the Horbach-Keele matrix. \\ **Options:** Number of ways, vertical club, etc \\ **Use:** The Horbach-Keele crossover is a special case of the purely digital, phase-linear crossovers. It is used for fully active & digital D'Appollito arrangements that are exclusively vertically mirror-symmetrical. By deliberately overlapping the outputs of adjacent drivers in both time and space, a controlled constant directivity is generated in the vertical beam axis. \\ **Example:** [[http://www.linkwitzlab.com/Horbach-Keele%20Presentation%20Part%202%20V4.pdf|http://www.linkwitzlab.com/Horbach-Keele%20Presentation%20Part%202%20V4.pdf]]
