I had the same "problem" about 5 or 6 months ago. Do you use a larger A/T screen and put the speakers behind it, or do you use a normal, smaller screen and place the speakers beside/below it? i was limited to 12' width and had to choose one or the other. I chose the latter personally, I went with a 110" diagonal when I was hoping for more like 120". I sit about 15' back from it. I just have a hard time believing the screen doesn't affect sound quality, and we do know the screen affects picture brightness. I just was not willing to sacrifice both audio and video quality to gain less than 10% in screen size.
Of course your opinion may differ and I know many people are happy with A/T screens. I do recall reading a test someone posted here once though where they tested three screens, and the only one that was decent was about three times the price of the others.
