Something that needs to be mentioned is that the MM2's and MM3's drivers are all in the same positive polarity. The Maxx 2's and the Maxx 3's have the tweeter and woofer in positive polarity and midrange is inverted. This could explain the difference in what one hears between the two speakers. IMO
I currently own MM3's and have owned Wilson Watt Puppies 5.1
