My family room is 16 x 20 with the couch on one side of the long wall and my system on the opposite long wall. Right now, I have my sub in the corner to the right of the couch and I can tell where the bass is coming from vs my main speakers. My system is across the room against the opposite wall with openings to other rooms on either side of the system. I can move my system (a major pain)to the couch wall which would allow me to have the sub to the right of the right main speaker rather than beside the couch. I know I could move the sub temporarily to hear the difference without moving any future but the wall with the system has no corner. Any comments? Have any of you moved your sub from beside the sitting position to beside the main speakers? If so, did the sub blend in better? And did you hear a big difference?
