Blown tweeters

You may only need to change the Ferro Fluid in the tweeters, of so equipped.  Easy to do in an afternoon.  Do a little research to save yourself a lot of money!

How old are the speakers?  Most speaker companies have a five year warranty on parts. Some even have ten year warranty’s.

What amp were you using?  Could you have been over driving it? That will blow tweeters fast if the amplifier is clipping.

The speakers are 20 years old my amp is a rotel rb1090 and pre amp is a prima luna dialogue cd player is musical Fidelity A5

Who "upgraded" the crossovers? If too much midrange gets to those drivers they will blow. The solution is going back to the stock crossovers. Trying to put a different driver in there with a passive crossover is a crapshoot. The efficiency of the drivers has to match perfectly which is highly unlikely. 

Put the crossovers back to stock and order a new pair of tweeters from the manufacturer. 

Mike Farnsworth the owner of talon did my crossovers and I played speakers for about a year before the tweeters went
