Joe, welcome back. The QS8 back surrounds should be near the back corners and maybe 2' down from the ceiling. If you meant possibly using the front corner wiring for the other QS8s, that wouldn't suit their purpose. They're side surrounds and should be about directly to the side of the listening position, as you apparently have them now. So placing the one on the left near the equipment wouldn't be a problem. Could you also run the right side surround wiring from there across the room under the carpet(if there is one)and then a few feet up the wall? Or, take the right front corner wiring and extend it back along the ceiling and down a couple feet?
