Well, I got them hung. I did find some studs, but had to make some compromises. Not sure if I like it, but it seems to be working so far. I'll try to post some pics tomorrow. I went with 7.1 even though my room is a bit small for it, wider than it is longer. But I figured I'd get the speakers now while my wife was agreeable, so when the basement is finished and I move down there into a bigger room I'll be all set.
