Magneplanar 1.6 QR's problem


I have a pair of Magneplanar 1.6QR's purchased new in 99/00. I had them in storage for about a year and hooked them up today. One speaker seems to have no mid or highs. Fuse is ok. All else in the system works and nothing else has changed. Any ideas?

Mofi is right - check the tweeter attenuator jumper. Also take the fuse from the working mid/high speaker and install it into the questionable speaker to be sure.
you can take the back plate off easily and look around for loose connections etc, if you have not done so already...
OK I have swapped fuses between the speakers, removed and reinstalled the jumpers and still no change. I will get new fuses today but that's not it. I called Magnepan and hope to get a return call to see if they can offer advice. I'm puzzled.
