I can chime in a bit here. My qs8's are on the side walls (in corners), facing inward, and roughly in line with my ears when seated(although elevated). If you sit under the woofer, it is distinctly noticable. I found one way to alleviate that somewhat was to angle the qs8s just slightly downward using the full metal brackets, so the woofer fires into the wall. All in all though, they are pretty forgiving. My vote would go to "A" but make sure you calibrate them once they're up, it makes a big difference! With "B" you will definately hear the bottom woofers distinctly.
