Here's my only option for a 7.1 setup so far as I can see. The images are not to scale. but they help picture the setup. All windows are floor to ceiling www.wcarrot.demon.co.uk/me/sevenpointone.jpg www.wcarrot.demon.co.uk/me/fivepointone.jpg I'm using TDM34DS's. All 4 surrounds would have to be wall mounted approx at 8ft (2.5m) to the top of the speaker, which is around 10 inches (25cm) from the ceiling. The Rears would be in the way when walking to another room if they were lower (radiator on wall behind main sofa doesn't help either). The nearest point of the right SIDE surround will only be around 6-8 Inches (15-20cm) from the rear wall, but I could place the left side surround further forward. The sides are quite a way behind the viewing position and a too close to the rear wall. I was going to wait until my new room to go 7.1, but my Lex on it's way is making me impatient. Because of family considerations there really isn't any other positioning option if I want 7.1 in this room. Should I stick to 5.1 which sounds great at the moment? I'd really like to use Logic7. Any input on this configuration please? Cheers, Mark.
