Ok so heres the deal. I have the HK avr 630. I am setting up 6.1 (NOT 7.1) and here is my question/problem. For rear (6.1 or 7.1)speaker hookups on the 630, There is SBL, SBR. So what I want to know, for 6.1 how should I hook it up? SBR + and SBL - ? one or the other ? I emailed HK on this and the answer was "Hook up 7.1, its better". A. I dont really have the room for 7.1 B. I know that unless you have a perfect room, acoustically 7.1 is no good. C. Nothing is in 7.1 Here is quickly how my rear setup is now. Center seating, rears are angled to the center, 1.3M speaker to center. 2.9M apart. Room width is 3.0M. So since the width of my speakers are 0.3M, its easy for me to place one rear center, but going 7.1, I am not going to have much/any spare room behind my seats. Plus I CANT put my rears on the sides. So there it is, Please give my all the info you want to give me on this. Any tips, advice, anything. Thanks alot, Scott.
