Let me begin by saying that I am a novice on a budget. Due to the dimensions/design of my room, it is not feasible to run wires for surround (rear) speakers. For this reason, I wanted to go with a 3.1 set-up. I currently have a LG soundbar connected to the TV via a optical cable (only option) and a wireless sub. What I would like to do is find a receiver that could utilize the soundbar as a center speaker and add a bookshelf speaker to each side of the TV. Is this something that is possible? If so, are there any receiver suggestions?
