Steve, a couple of questions:

1. How are the M5s in the bar area used? Are they for background listening when sitting at the bar? How far away are they? I presume the bar is separate from the theatre? Are they in 2.1 or 2.0?

2. Are the QS8s rear speakers in a 7.1 arrangement? Are they making an audible difference to your experience?
