Sorry it is for 5.1 configuration and the back wall is not an option due to a closet door on the back wall which goes all the way to the ceiling. I cant use a stand because I have a sectional sofa on the other backwall. I believe i will do what you suggested and buy the QS4 and place them on the side wall a foot from the back wall. They are mostly for movie watching except when I have a get together and we play music. And Im sure there more than good enough for that. Thank you for your very specific recommendations and advice. buy the way do you recommend the metal mounting brackets for the front two and rear surrond speakers. The center will be on top of the TV?
