Where can I buy those posters saying that this theater features THX and DTS SURROUND SOUND?

Not sure if you want actual poster size or a sign, but check this thread if you haven't already:

They come up on ebay at times. These posters aren't cheap....plan on spending avg of $50 for double sided versions of these posters.

PS: There was a time they were available through their official sites...THX and DTS. I don't think they are any more.

The theater posters are 27X40. They are pretty big. There are some really high rez files floating around you can use to make your own 8X10 or 11X14 pics. If you want posters you are going to have to pay. The DTS isn't as bad as the THX but both are REALLY expensive (40-80). The one cheaper option is Dolby. They sell direct and have a 4 pack of posters, three of which are double-sided, for $20. I've been thinking about it for a while myself:
