I should've mentioned, that front door will probably not be used at all. In fact, I could throw a couch in front of the door and it would be no problem. The entrance used will be through the garage & kitchen.
The problem setting it up the wall opposite the door is that there are bedroom doors on that wall which aren't apparently in the little "blueprint"
You can see the one bedroom door in the second picture.
No real surround needed. this is a 2 channel system
I was thinking the 12 foot wall opposite the kitchen myself. What is a good distance for the listening position? I could back the couch up against the other wall which would give me roughly 8-10 feet of distance between myself and the speakers. What is a good spread for the speakers? I take it I shouldn't have them too near an adjacent wall to avoid a loss of imaging? I imagine I should have them kicked out from the wall atleast a foot, foot and a half to allow the rear ports some room to breath..
Edit: new response
Thanks discgo, I'm intrigued and will check that article out right now!
