Incidentally, I was able to review all the Axiom speakers M40 through M80 at Replay Electronics in Toronto a few months ago. I dealt with George at this shop and he was extremely helpful. He put all their speakers side-by-side for comparison and I was able to differentiate between the sound quality of each of the speakers mentioned in this thread. All the Axiom speakers sounded good. However, when I did a side-by-side comparison between the M60 and the M80, I found that the sound from the M80 was bass(ier) and it went lower. Further, the M80 had better dynamics. I ended up buying the M80Ti's and am glad that I did. I have had them for about 3 months now and am enjoying them immensely. I have them hooked to my Onkyo TXDS 797 receiver and am amazed at the amount of bass the system throws out. I am not sure if I would need a sub-woofer now.
