I currently have an ancient Pro Logic receiver (3 front channels + mono rear) which I will upgrade when funds permit. I just moved into a new house and for now I'd like to get the rear speakers set up. The room is about 19' front to back and about 12' left to right from the perspective of my recliner facing the TV. The TV is roughly centered on the wall and my recliner is across the room, up against the back wall. I'd like to install 4 rear surround speakers in advance of getting a 7.1 receiver but use just the right/left surround speakers until then. Questions: The diagrams I've found online show the right/left surround speakers straight out to the side of the listener or slightly behind. How bad would it be to have those speakers slightly forward of that? So they'd be along the side walls of the room, 2-3 feet from the back wall. I'll be pretty much right up against the back wall of the room when I'm watching TV. I'm trying to avoid having all 4 surround speakers lined up along the back wall of the room. That's bad, right? How much better is 7.1 than 5.1? With my placement constraints, would I be better off just going 5.1? All of the surround speakers will need to be ceiling mounted. What are some good, but not too expensive, and smallish speakers I can use for this. Something about the size of the Bose 2 driver satellite cubes, but not Bose, would be ideal.
