Magnepan have not changed much over the years. My first set is from 1975 and they are very similar to the set from 2003. They still seem to use the same basic ingredients like magnets and wiring. I am really not sure they changed that much of their ribbon drivers. It can still be same magnets and ribbon cage....
My mids were damaged in shipping. There is a german company that has suitable streching jigs and they can give the new Mylar the tension of the original.

The mids of the T-IVa are the only Magnepan with 6µm Mylar diaphragms. Compared to the 3-series, the diaphragm is divided into smaller sections, giving each a very small moving mass. Bass will not pollute these mids as in models that share bass and mid on the same sheet of Mylar. Tympani basses have less moving mass than the 3-series. Up to 250 Hz is really not much of a problem.
