Concerning the on-walls, I'm not a fan of them after I tried them, but there are many more that like them.
I don't have room for floor standers in that spot, so as a compromise, what I intend to do is mount bookshelf M22's on the wall to the mid to lower left and right of TV, then mount M2's to the upper left and right of the TV, then mount VP150 under the TV. All bookshelf speakers, and all in Cinnamon Beech to match the sub-woofer. I'll reuse the black on-walls as surrounds, mounted on the rear wall. Seating is mid-room. The current set of M22's and the on/in-wall VP100 won't have any use for them. Probably sell them.
The reason I think I'll like the M2's mounted above the M22's is I think that it should increase the wall-of-sound value. At least it does with the on-wall M22's when I'm using both the bookshelf M22 and on-wall M22 at the same time, vertically aligned.
