No one can provide specific screen recommendations without knowing what projector you intend to buy, what screen size you want, your viewing habits (3D?), and how much you're willing to spend. Obviously there are more options available at the $5000 price point than there are at $500.
If I were looking for an AT screen I'd start with a forum search on the words "acoustically transparent". That will turn up plenty of threads on the topic. A general Google search on "acoustically transparent screen" will find many more. Reading about what's available, pricing, reviews, and owner impressions should allow you to narrow down the field. If you contact one of the reps at the AVScience store (the folks who host this forum), they can provide guidance if you tell them what you want and your price range. email@example.com has been very helpful with my orders. AVScience has other reps who can also help with guidance & pricing.
After you've narrowed down the field to a few possibilities, email the manufacturers and request samples. Comparing samples should allow you to judge what's best.
