Josh, Get hold of a Apogee Scintilla MRT unit, its foil only ribbon and solve the issue, Its the best other than a FR unit

As I understand it, the problem with the the foil midrange ribbons is that they get metal fatigue and fail. IIRC, someone from Apogee said that a high number of ribbon failures contributed to its demise. Years ago, I asked Mark Winey, and he said the same thing -- you can't make a robust one because of metal fatigue. (The Magnepan tweeter ribbons can also get it after several years if you play them at natural levels, but few people do. They last like forever at lower ones.)

  has anyone at Magnepan, to your knowledge, experimented with metals other than aluminum? I would think certain other metals would have significantly less fatigue problems than aluminum, while still being reasonably conductive. Aluminum has a well-known low fatigue tolerance. I ask these questions in the setting of being very far from highly knowledgeable on metallurgy.

    Possibly, but if they have, I've never heard about it. Mass is absolutely paramount here and that in and of itself places a limit on the metals that can be considered. But I'm no more a metallurgist than you are, so have no idea if there's something exotic out there.

Doesn't the Apogee Scintilla MRT unit need a lot of power at a very low impedance?

    Well I don't find them any worse than a Magnepan, a lot of the amps people are using here, will drive them just fine, UNLESS your death of course. I listen to mos music around 75 db :)
