I'm hoping to pull a driver out of my M80HP and post an image of all three this weekend.
There should be obvious differences between all 3 speakers(stamped vs original cast vs HP cast). I'm hoping his statement about being equal to the original cast basket is proven to be incorrect.
Either way they sound great, its more about my expectations when I purchased them. There was talk of a new driver for the M100 and I don't recall/can't find a statement from axiom that confirms they are in fact different from the original cast basket upgrade. Stay tuned...lol
