I would just use the flush mount T bracket that comes with the QS8's.

I have my QS8's on the back wall and they sound great, see link below:

The far seat on the love seat is kind of odd because it is so far away from the right surround, but the left surround is directly above you- the other seat on the love seat is decent. this is not a big deal b/c i really don't have that many people over when watching movies

All seats on the couch sound excellent.
