i couldn't help notice that there's no real discussion about the m50 in the forums (infact a search turned up no threads).
is it the bastard stepchild of the product range?
Unfortunately the search function isn't working 100% and it's not finding any threads.
When I was at the Axiom factory they had M50's and M80's hooked up for A/B testing along with the EP500 and EP600 also on A/B testing.
The 50's are very nice speakers and what I was originally looking to buy. Due to them not having the mid range driver(s) the 50's seem a little more laid back and the bass more pronounced. I think that the 50 is a more forgiving speaker and a very nice one. I just wanted that little extra clarity and overall smoothness of the entire sound though and opted for the 60.
