I've decided not being able to get the 9 speakers I want is a good thing and I've come to terms with using the same budget on my mains and surrounds.
I took some advice from "honest opinions wanted" (1) and have found some interesting speakers I'd like opinions on.
The QS4 from Axiom looks like it would be perfect for the rears. I'd probably install them with the bottom of the speaker 60" off the floor at 90 degrees. My room will allow 90 or 120 (there's a door in between with no header).
Too bad a guy didn't have more money laying around...
