Hi BruceH,

Looking at your diagram, I wondered why the two extra surrounds (for 7.1?) aren't located behind the seating area, which is where they are intended to go if you are running 7.1.

But perhaps you are running 5.1 with multiple surrounds for better coverage? If the latter, I don't think you'd need to angle the rear QS8s towards the listening area. Their very broad dispersion depends on reflections from a variety of room surfaces. Try it both ways.
