My M3tis, VP150 and QS4s just arrived today! I couldn't be more pleased. The QS4's were supposed to be factory outlet, but I can't find a flaw on them anywhere. I have a quick question for anyone regarding the QS4 placement. My room is 11 1/2 feet by 22 feet with the listening position around 8 feet forward of the rear 11 foot wall. I would like to wall-mount the QS4s on the side walls around 3 feet above the listening level. Am I correct in assuming they mount flush to the walls and therefore point toward each other or do they need to be pointed forward? Also, how the heck do I mount these things? I'm not understanding how the brackets on the speakers work. I apologize in advance for my ignorance. It's my first HT.

Thanks
