Creates a crossover network (XO files) similar to the Generate → Crossover function, but in the Horbach-Keele matrix.
Number of ways, vertical club, etc
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.
