My living room surround amp is actually a 7.1 but I've never used it. Put it on 5.1 when I got it and kept it there. I have one extra JBL speaker I never used. I'd need another one if I want to go to 7.1. And I'd have to wire up which isn't so easy. That's why I haven't done it. Does 7.1 really add anything worthwhile? What sounds do you get out of it? Same as the other two back speakers?
Not much really. I've run the receiver through the different settings and can't really tell when they aren't working. That's the main reason I'm not to bothered by it. My wires are along the wall around the room.
