LJ39,
congrats for both, your system & your skills!
Very nice indeed. By the way, regarding to your SB speakers, I do have quite a similiar setting as yours and what I've done was to mount the speakers on a "made by myself iron brackets", both facing 30 degrees down and tell you what, it sounds pretty amazing. I did the same on the L/R surrounds as well (see the attached shots). Considering the "pedigree" of your speakers, you don't need to buy another pair osf speakers, just because of that issue.
In the meantime, enjoy your new HT!!
Cheers / Avliner.
