Here is my dilemma. I have a room for my HT, but it has no usable side walls. So I will do what I did the last time and go with surrounds placed slightly behind and above the seating area. I was considering in wall speakers because of asthetics and WAF. I know for sure that in-wall speakers are inferior (sound quality-wise) to most inclosed speakers, but since I am only using them as surrounds would that be acceptable? I am also concerned over using them on a hollow sheet rock wall that is 12' ft high. I feel as if the sound would die in the wall. Again, I think it might not be that noticeable because they are only producing ambient sound for HT applications. Bookshelves mounted to the wall would also work, but would look awkward. If push came to shove I could mount bookshelves to the wall, but I am not to sure which way to go. Onto question 2. Should I go with 6.1 or 5.1. All the reading I have done suggests that unless I point the center rear surround to the listener in the middle, it would negate the benefits. There is no way I can point that rear center to the middle. It would require mounting to ceiling and pointing directly down. Knowing all this, should I just stick to 5.1 All suggestions and comments are appreciated.
