So, assuming that your TV is sitting at the center of the 11-feet wall, you have over 3 feet of room on each side of the TV, right? In that case, my first choice for the M22 placement would be right in the middle between the TV and side wall -- NOT right next to the TV or to the side walls -- and perhaps a bit forward of the TV screen. The M22 will sound better when isolated from other surfaces reflecting sound.

[wow... I didn't say anything about front projection here! Or did I? ]
