You're right, JohnK. I use those for HT, with the M2's as rears. But I'm planning to get 2 speaker pairs for the living and dining rooms for music. (I think that'll be cool, especially for easy listening when I have friends over.) Hence, my query about how the M3 and M2 compare, without a sub. What do you think? And how much distance should I provide from the wall? Thanks again.
