In my own personal experience with the m22's, having the tweeter at ear level has been the best sounding position. I don't have the axiom stands yet ( the ss16's are what i've decided to get, i'm using some makeshift stands temporarily) but for me, sitting on my couch, elevating the speakers by 15 or so inches is just about perfect, and stands that size should be pretty stable, especially with the decent weight of the m22's. I don't think 15 inces is that high. While I have not experimented with a stand that would place the speaker at floor level and tilted back to aim the tweeter at the listening position, I would think that this would also be much better than just having them on the floor with the tweeters aimed at your knees. Just my $0.02
