My sectional is about 1.5' from rear wall. This weekend I will be connecting my JBL E10's and mounting them to the side walls. I have JBL N24's that I am going to use on stands for rear surrounds. Sicne their is not much room behind my seating position, I am thinking of having them firing up towards the ceiling. I know some here have reco'd that, so I would like to hear some more opinions of those that do it, how you mounted your speakers (or what they are sitting on, how high off the floor ( I was thinking of having them just below the top edge of my sectional-just out of sight when looking straight on). Opinions on your findings when firing them forward vs ceiling appreciated, especially if your seating config is similiar to mine. I also have the option of mounting my E10s, directly on rear wall about 4-6' apart and using the N24's on stands off to the sides, but have not made up my mind yet. Receiver is a pio 811 which does 6.1, but has connections for L/R center surrounds. Thanks.
