I'm considering purchasing the epic grand master 5.1 system, with the qs8's, vp150 and m22ti’s. However, I have a small room and my couch, the main seating area, is on the back wall. Also, the only arrangement that the room will allow for surround speakers is on the sidewall in the corner. I may be able to get 2 to 5 inches spacing from the back wall, but they will be still nearly in the corner. The tweeters are angled at about 45 degrees, so the tweeter firing into the corner will reflect off the back wall and end up in front of the main seating position. What kind of problems can I expect from this setup? Would it be better to go with a bookshelf speaker for the surrounds?
