Crossing over, with Gallo Nucleus reference

Well, I am here where I thought I would be. I have one Nucleus opened up and in a state of non-function. It appears that there some sort of a custom "high pass crossover" that interrupts the tweeter. This was a melted mess, when I opened it. Not much in the way of identifying marks. Anyone have any ideas on how I can salvage this speaker? Tweeter still works. The techs at roundsound.com offer No advise.
Any help would be greatly appreciated.
