Hey guys - I'm trying to plan speaker placement for our living room, but it's a somewhat weird layout. Because of symmetry and the wife's insistence that no furniture be moved, the sofa has to stay where it is. I've attached two pictures and a rough (sorry!) room floor plan. The Boss has also dictated that if I do this, the speakers cannot be on the walls down at close to ear level (where I've told her they should be). They have to be up higher and aimed down at about a 45-degree angle. The room is about 20' x 17'. Our heads are about 3.5' high when sitting, and the ceilings are 10' tall. I'll probably be going with the HT-S9300THX - yes, I know for ~$800 I could probably build a better component system, but that's for another thread! I've put 4 red circles where I think the sides and rears should be located. Also, in the second picture, the sofa isn't quite as close to that side wall as it looks in the photo. That listener will be about 5' away from the speaker, with the speaker approximately 4.5' above their head. I'm concerned that speaker "D" will be too close to that right-side listener, and that it will be too high at 8'. I'm also worried that speaker "C" is too far back. "B" has to be on the far left side of that wall, since we'll be putting a large bookcase there in the near future. I could place it over on the right side of that wall on the corner. What do you guys think?
