Thanks guys! I'll make rough up some stands with 2x4's and experiment a bit before the final mounting.
Also, I'd just like to say that this is a great forum community. It's nice to have folks who are passionate and so willing to share experience and ideas. Cheers to you all!
That's a good idea! Just so you know, the THX specifications for the side surrounds actually recommend that they go on the side walls a bit forward (towards the screen) from the listening position. However, this basically assumes that you'll be using one or more rear surround on the back wall. Nevertheless, I'd try both -- and give preference to the side walls especially if I thought I'd ever possibly want to install the rear surround(s) for a full 7.1 or 6.1 system. If you're sure you never will, or don't mind potentially moving them, then the rear wall is fine too.
