Hey Krich,
That's a very helpful diagram. I prefer the green placement option, with blue second.
If you want to keep them "low profile" then I would go with the blue option. This way you can use the standard T-bracket wall mount. The QS8s look very nice flush to the wall, even better if you can hide the cable behind them completely. Also a less expensive option than using the full-metal bracket. And it looks like this way you can mount them 1 or 2 feet above the listeners ear level, vs. close to the ceiling, so you won't have to tilt them at all.
Whatever you end up doing, the QS line is very accomodating and will perform great. So do what you think will be best for your room and then enjoy.
