Finally got my 15 posts so I can post URLs. I need some advice on configuring my living room for best sound quality. Thanx to all who have been so receptive to newbs such as I thusfar. Living Room: My house (new) was pre-wired for 5.1 surround sound...the 5 red circles show the wiring blocks in the wall near the beginning of the cathedral style ceiling up top. My tv is on a small entertainment stand where the blue rectangle is, and my couch and love seat are placed as shown also... I am going to use Sonance Speaker wall mounts to mount the speakers next to their appropriate wiring blocks on the front (tv) wall of course aiming slightly inward and down. But I'm not sure what I should do about the rear wall...the fireplace area does not have a squared top...what you see there for that diagonal line in the corner goes all the way to the ceiling like this: You can see the blank wall plate that has since been replaced with a wiring block to give you an idea of what I'm talking about... My biggest question though is should I mount the rear left speaker next to the wiring point right above the couch or should I mount it centered above the fireplace or should I mount it to the right of the fireplace? or is there some other place? I wish I had a better place to put the love seat because I hate it being in front of the window like that...but...I dont' see any other option...the furniture isn't necessarily to scale. The front door into the house is the one at the bottom, and the one on the left wall goes to the spare bedrooms...the door at the top goes to the kitchen. Any ideas?
