Having reversed your panels, you will notice that there are no longer any 'bars' in front of the ribbon. Magnepan puts those bars at the front, IMO, simply for protection - but the way I see it, they must be causing diffraction of the ribbon sound. So much better to have a clear slot in front of the ribbon. :-))
And if you ever get round to replacing the stock MDF frames, put the rebate for the ribbon cage at the front of the frame - so that the surface of the ribbon cage flange is flush with the front of the frame.
Magnepan, with the 3.6:
a) increased the size of the mid panel (compared to previous models), and
b) flipped the bass-mid driver so the mylar was in front.
I believe the 2nd action directly followed on from the 1st - they thought to deliver more mid by making the mid part of the shared mylar sheet, wider ... and putting the mylar at the front, further enhanced the improved mid range.
Unfortunately, though, the bass driver shares that same sheet of mylar ... and there is good reason to have the magnets in front, for the bass panel. :-((
