Can anyone please provide or point me to an absolutely correct schematic for the charge coupled crossover for a 4355 system. I have read a number of threads and posts that have shown schematics or drawings of the crossover only to find out later that they were wrong and corrections have been made.

I have completed the speakers and trying to get the crossovers completed only to find that the schematics I was following are incorrect.

Any help greatly appreciated.

Here is the actual stock schematic:

It might help if you posted what you have been using. If it were not for the taped inductors it would be a simple conversion. You are probably using an equivalent with the same voltage drives with the taped inductors designed out of the mix.

That was the last version I know of that I would trust to be correct

Thank you for the schematic. That enabled us to complete the crossovers without any further problems. Much appreciated.
