Ohm Walsh's! I have a pair of the older Sound Cylinder's set up in my front room - actually in positions where conventional box speakers would sound awful. The SC's sound pretty damn amazing! No matter where I stood I had the uncanny experience of the "musicians in the room" effect!
Ohm walsh or focal domes
If you could either get ohm walsh 4000s and set them up suboptimally (one on the left but the right one farther to the right and slightly behind you) in a large great room with vaulted ceilings that opens up to the kitchen, or get a pair of Focal Dome Flax satellites with a nice subwoofer and set them up properly to the left and right in front of you, which would you do. Go!
