Maybe closer to two feet from the face to wall...the Yamaha towers are 14 inches deep.
The system is used 100% for tv and movies....streaming on Netflix is the largest use.
I can't move the speakers out much....there is a coffee table in front of the couch and that cuts down on the thru traffic area already.
I'm going to try getting the sub to work better first. The pic below is the back of my old Advent...I don't see anything on it that would make it better than the Klipsch.
Thanks.
