I have been using some black speaker grill felt for the walls in my room so that I can have black walls and not effect the existing accoustics (which seem fine so didn't want to alter anything). It's an accoustically transparent material like ordinary speaker grill material, but being more like felt it is more of a matt black and has no shine like ordinary speaker grill cloth.
I think I would try to use that if I were to have an AT screen and all speakers behind the screen. I may use some plush black velvet for the edges, specifically for the edge that will be next to the projected image, and make sure the speakers were just outside of it so the audio wouldn't be effected. Here in the UK we have a retailer called Maplins that sell it, so you may have something similar In Oz (Radio Shack in the US would be their nearest equivalent I guess).

I trust Gary Lightfoot more than James Cameron.
