Blown tweeters

I did he was stumped as to why both speakers would blow tweeter at same time

How do you know they are blown, by the way? 

Often we don't even hear when a tweeter goes out.  A midrange though... :)

In any event, lots of things can go wrong before the tweeter.  If you wanted to thoroughly diagnose it, get a Dayton audio DATS V2 to measure the impedance of your whole speaker a swell as the drivers out of the box. 

One step below that is to remove the tweets and test with an Ohm meter.  See if you have a short (no Ohms) or open (overloaded or infinite Ohms) circuit.

My speakers have a 10 in woofer a 1 1/2 in tweeter and a 1 in tweeter the 11/2 in tweeterc  is blown on both speakers I put my  ear right up to driver and no sound out of larger tweeter

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!
