I am also trying to decide between these three systems, either the M22's, M40's or M50's all paired with the VP100 and 3 QS4's. I will be using the Outlaw 1050 (rated at 65w into 6 channels) as the reciever and am anxious to hear the outcome of this post. I am leaning towards the M40's or M50's due to their floorstanding nature and the fact that I have young children. My room is 11' x 18'.
