I rebuilt my speaker crossovers which only had a capacitor for the Mid and a capacitor for the tweeter. No resistors or inductors.
I chose Duelund after reading Tony Gee's comparisons (see attached link)http://www.humblehomemadehifi.com/Cap.html.
I changed the internal wiring to Vampire at the same time and also re-calculated the capacitor values with the help of Rodmann on Audiogon and the calculator on the following link http://www.apicsllc.com/apics/Misc/filter2.html#first
The improvement to the sound was astonishing.
Good luck.
