Supposedly this already happened. All new 3.7s after a certain date were I models. I read somewhere else that the change was bass panel tensioning. As an upgrade mod this would probably require a new bass driver, not a simple xo change. At best, removing the bass panel assembly and taking it apart further, and reassembling in the production jig. Note that the tensioning has always been an important Magnepan trade secret. It is not uniform across the height. Apogees were trapezoidal. Maggie's aren't, but they behave as if they were a bit, and for the same reason, smooth resonance modes.
I don't understand why everybody is bitching. They made a modest production improvement and run their business as they always have.
