Blown tweeters

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!

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
