I finally got my receiver shipped to me the other day so I will hook it up tomorrow but I have a couple of questions on speaker layout. I was going to try the 9.1 setup using front wide right an left speakers since I have high uneven vaulted ceilings I don't think atmos will work very well. Now since I'm only using one zone it says I can add two more channels to make it 11.1 can those extra channels be used as front presence speakers? (Since I have them hanging on my wall) I also plan on adding another sub down the road. Thanks for your help
