Fried crossover or bad tweeter?

Congrats on taking the plunge and doing it yourself. It's nice the parts are available.

Well done!

I called B&W and was able to get a diagram of the speakers and some advice on how to remove the tweeters and took your suggestion.  
I swapped tweeter domes (remarkably easy once you know how to open the tweeter enclosure) and the problem remained the same.  

I just ordered a new mid-range crossover from B&W.  At $86 I think its a bargain to keep these speakers in use.  

Fingers crossed that the other crossovers don't go out soon!

I'm no technician, but, if you have the time, you could swap tweeters (or crossovers), if it's not too much work. That should tell you what to replace.

Best of luck,
Dan
