The reason for the side surrounds being in there spot is because on one side by the back porch (opposite of the 16x10 arch) the windows will be fully encased in trim from the floor to the ceiling. So there is not a spot for a speaker. That little spot the speaker is drawn in is between the window and the door. The sofa may be back a little more depending what it looks like when all setup but it would at least be 16' back. I could hang them from the ceiling and have them in front the window casing but I don't want that look again. My current setup had them hanging from the ceiling.
So I could do qs8 on the back wall....I'll give that some thought too. I'll pull them a little closer...right now they are about 7' apart.
Thanks for the input! Anyone else have something to add?
