I have decided on B&W 603 s3 for my 2 main, lrc 600 s3 for my center. I have 3 choices for my rear, they have to be mounted on the wall, I have a 24 X 24 room and power my speakers with a Denon 2805. The 3 I am looking at are the M-1, 600 s3, or the more expensive DS6 s3. I listen to my home theater more then music. Any help?
