Building a 5.2.4 system for a customer. The room is 17 wide 13 feet deep. He only wants a 65 inch tv. The room layout is open space build. Behind the living room goes into kitchen and dining space. Side surrounds speaker have to be at 12.2 feet. After that is studs and glass door 8 feet on one side other is hallway. So he wants to sit between 13-14ft back. So he's behind the surrounds. Has anyone had a customer like this? No idea what to do. Told him it will sound like crap being behind the sound.
