Randy,
I had read the review that said sliding to either cushion other than the middle on the couch caused the clarity to drop off noticeably. I never posted concerns like that during my prepurchase "sweat it fest" - but the thought was in the back of my mind. In practice, I do not find that to be the case - and my couch is directly centerd and facing the 150. So - again, all my sweating it was for nothing......Rob
