I have been pondering on if I could get full 5.1 sound in my living room. I have thought a lot about speaker placement but I cant work out if it can be effectively done considering the layout. Here is a picture of the room layout (apologies for quality and scale is off. ) The problem I have is with the rear speakers. The sofa is right up against the wall, and the stairs. There is no where to mount the left rear speaker unless it is on the wall behind the sofa but it would be directly above where I sit (the left side). The right speaker could go to the right of the sofa and high up I guess but would this work or would it be unbalanced. Also if the left and right rears were on the wall behind would the fact that the left and right fronts and centre are at a 45% angle to the seating position make balancing the sound impossible ? Thanks for any help / advice. I want to know if this is possible before investing in the gear.
