I've been watching the XPL related posts for years, I don't recall any x-over upgrade posts. We don't even have the schematics for the original version, only the second version. We do know that the caps are already bypassed, and that many of them even have two bypass caps.

After taking apart the stock XPL200A network and measuring all the DCR values and then pricing out charge coupled networks I came to the conclusion that they didn't warrant the effort.

Sorry 4313B ,

Do you mean changing some caps etc ... would not make a real change and there will not be real added sound quality ?

I think they could definitely benefit from charge coupled networks, I just didn't personally pursue it due to time, size and cost.

If they are going to be your "last pair of loudspeakers" then it is probably worthwhile.

I would probably look at building them external.

In fact I realized when buiding a charge coupled network fro my 434x ( clone copy of "John W" nextwork , thank's to him ) , the result was very good with a lot of details and clarity .

Now My 250 clone using 093 and aurus cantum tweeter and xpl200 network bi amp made good result with a big improvement on the tweeter side versus 035ti but I feel There is something to do with the network !

I think I better wait for someone who will build an xpl charged coupled ; I can only make soldering but unfortunately not the network schematic !
