Mirage M-1 tweeter died, No longer stock. Help

I don't quite understand, if the tweeter doesn't work, isn't your system already down? You can remove the tweeter yourself and send it to them. If it is a front tweeter, you can take one from the back and put it in the front and continue to use the speaker. I doubt that you will find any company that sells a replacement as the M1 tweeter is a very odd shape.

It would be rather expensive to purchase another pair of speakers just for replacement drivers and Mirage uses different size drivers for most of it's other series. I think you should take the tweeter out yourself and send it to Mirage for repair. I've replaced a few of these being a former Mirage dealer and I still own a pair of M1's. It's a little aggravating but not too difficult to remove the tweeters. All you have to do is take the tops and sides off and unscrew the strips of wood that hold the grillcloth on top and roll the fabric down to get to the tweeters. The screws are under the damping material covering the flange. As I said before, you can take one out of the rear and put it in the front if you need to and continue to use them until the speaker comes back from repair. I have done this myself and it works fine.
