Well I got the EZ anchors and a stud finder. I placed them in and it work great. Very secure but I won't let anybody try and hang off of them
I did find it difficult to align the hooks when placing the QS4s onto the bracket. it took several tries and a few marks on the wall to get them in. They look good on the wall but it's too bad it is so difficult to position them.
I hope to have pics up for viewing in a few days but I'm still trying to sort out the wiring and make it look tidy. Most people have the large speaker, large room setup so I think it'll be helpful for some others in a similar situation to see a small room small speaker setup like mine.
