Trevor, no worries ... you have some good points. I need to have a listen in a smaller more conventional space. Haven't had the time to set that up.

I really should not have posted anything on the M3c till I had a full understanding of what was going on ... I do think I can safely say that the M3c is a big compromise sound-wise vs a M3 bookshelf or on-wall. If some of that is solely because it is ceiling mounted so be it ... that's part of the compromise.
