Happy Superbowl.

Ok so working on getting my system set up corect I found that one of my old M22Tis (from 2001) no longer works at all. All the others work just fine.

Anyone have an old speaker go dead? They have been shipped and moved a lot but only one does not work. I have 3 ther M22Tis that work fine and a center VP150 that just keeps on without a problem.

Any Advice Welcome

Did you switch that speaker to other positions / amp channels to help ensure that it's not your receiver?

I'd pull the drivers out and look for a wire that's come off somewhere.

ditto what Mark said, I would make sure it is the speaker by trying to swap wires.

If all the other suggestions fail, you can then start swapping a crossover from a known good speaker into the bad one to see if the crossover failed. Chances are there is a loose connection from the main speaker terminal on the back to the crossover circuit board or something went terribly wrong with the crossover itself, odd to have both side of the crossover go dead.
