jordanz,

I would adjust until it sounds right. To be honest, I don't think there is a wrong answer here. The only thing I would do is to play with different angles until it's right.
I angled my QS8's about 75 degrees and roughly 150 degrees toward the sofa. It really depends on your layout.

Have fun!
