Subject:Leslie Crossover

I have built a passive crossover for a Leslie speaker which uses drivers
taken from an X77 Leslie. The classic crossover design as used in Leslie
147 and similar is unsuitable for these drivers as the bass speaker is
4-ohms nominal impedance whereas the classic arrangement had a higher
nominal impedance. Using the classic design would have shifted the
crossover frequency affected the filter characteristics considerably so
I set about designing and building one. If you would like to know more
