I'm setting up a new home theatre system. The receivers I'm looking at are all 7.1. I'm thinking about getting the Epic 50-350. My room is a finished basement with a very long back wall, but no side walls, so it's not ideal for a 7.1 arrangement. However, since I may not live here forever, I'm leaning towards getting 4 surrounds instead of 2 so I have a matched set of surrounds. Question: Could the four surrounds (QS4s) all go on the back wall? Perhaps having 2 spread out and angled in with the full metal brackets, and the other 2 mounted flat on the back wall, but closer together directly behind the listener? I know this won't be a perfect setup, but since I'll probably get the extra surrounds, why not set them up rather than just put them in storage for when I may eventually find a better room? I'd prefer not to use speaker stands. I have kids, they may get knocked over. Or, should I abandon the 7.1 setup and just go with 5.1 under these circumstances?
