Yeah, I can't wrapped my head around speaker break in but I can say these M80 on walls are really amazing now. The first few moments I heard them I was disappointed, to say the least. But I didn't know what I was doing, and still don't lol...But I do know that several hours of playing broke these guys in and they are exceptional. Having a receiver with a good DAC and proper amp makes a big diff too.
My disapproval with axioms V4 tweeters was directly related to the Yamaha RX-A860. It was a little better with the RX-A1080, but my EQ on the new 5200 processor has the high end flat, no adjustments. You can't hear the great potential of a speaker with an $800 receiver. It's a partnership.
