Who's modded modified speaker's cross -over?

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.

Wanna play around with what the crossover is doing electrically? Here is free circuit simulation software that runs on top of Pspice (if you care about that). Since it is a demo version it is limited to the number of components in the circuit. But this is usually more than adequate for crossovers. There is a bit of a learning curve but nothing you can't figure out pretty fast. When you build a circuit, you add a text to identify the nodes you want to probe, then run the AC analysis. It gives both amplitude and phase response graphs vs. freqency.
