I have both M3 in-wall, M2 on-wall and M22 on-wall (and some M2s and M22s regulars) for the non-Home-Theater rooms. I did not notice much (if any) difference between M22 on-wall and regular.

Because of look and integration, the on-walls is now my favorite avenue for future.

Of course, I would love a M100 on-wall! smile
