I think that the "rolled off or lacking" comment is because there is so much base coming from the speaker. The Axioms sounded great with Mozart, mainly because the the strings run through that piece but the M60 was weak when it needed some base backing. Again, vocals with the M60 were crisper but to my ears they were a little too high pitched. I liked the rockets because they seemed to blend the entire sound rather then just the highs.
