If your meaning, can a CC1 be made into a 2 or a 3, no they are not upgradable.
I don't consider a CC1 inferior in any way to a CC2, of course while there were some changes made, I never got a chance to make a direct comparison between those two.
I have however, directly compared the CC1 to the CC3 and find audibly, they are very much the same, although not identical. The newer 3 being able to reach down an additional octave, which makes it a bit easier to integrate with a subwoofer then the CC1 is.
Externally, the biggest difference you'll find is their actual physical size, the CC3 being about half as deep as the CC1 and showing the curvature of the diaphragm.
Internally, the diaphragm in the CC1 is a continuous curve, whereas in the CC3, it goes straight or flat across the front for about 9" inches in the middle. This change in design also helped reduce the more rapid bass roll-off that's present in the CC1, as well as adding that lower octave.
The CC1 is still a very good speaker, IMO, especially for the price they can be had for these days on the used market.
If your itching to upgrade...yes, you'll find the CC3 is unquestionably better.
Edit: Shoot! I just noticed you wanted a comparison to the MGMC. From where I was sitting with the question mark next to it, it looked like a 2.....Sorry, can't help ya. LOL
