My mains (the 20i's are floor mounted. My center is over the top of the TV at the present, working on moving that to below the TV when i find a new center speaker.
I have posted in the AVS forum and gotten a bunch of good ideas and information.
My wires are in the wall running up to the satellite speakers. How ever moving them or mounting wall speakers would involve alot of drywall opening up and rework which neither I nor the better half is in favor of. Things would be alot simpler if I had straight attic above the room but unfortnuatly I have a bonus room directly above the living room so there is not access without opening up the ceiling or the wall.
The link has a lot of good info. Whish I had had that when we had the house built
Thanks for your response though.
