Ok, then why do you want the JBL/Urei schematics?:duck:

If Ian doesn't pop in here send him a PM. He has been working on several active crossovers that are more flexible and significantly superior to the old Urei design.

Actually "I" would be more inclined to biamp with the woofer and arrange a passive filter b/n the horn and uhf.
