Have a rectangular room (13.5'x18'). Watch mostly DVDs and TV, but some occasional music w/o headphones. Nothing at very loud volume.
Should I just stick to a normal 5.1 setup with 200s directed at my seating area for surrounds? They would be about 1-2 feet behind and to the side of the back of our heads when we sit on our sofa. Or should I get some di/bipole speakers to mount on the side walls?
