The evolution of Proac Tablette speakers?

I picked up a pair of Super Tablettes and am pretty amazed by their ability to throw a tremendous soundstage.  Since the Supers were the second iteration and there are eight versions after these, does anyone have any idea what the difference in the various versions are (assuming there is one)?

I’ve searched and there’s not much info about the differences between the various versions.  I’m guessing more alike than different, but if one were to get a different version than the Super, which would be an upgrade, if you know.

Thanks.
