M22 box speakers if possible. Will cost a little extra for mounting brackets though, but I've had both on-wall and box speakers and I'm in the process of replacing my on-wall with the box type, because I just like the way they sound. But, if you can't or won't, I understand. It all comes down to a matter of personal taste.

Yeah, I've finally gotten around to working on mounting my upper 3 M22's.
