What are the best Room Accustic Treaments members have found?

There are many great acoustic treatment companies and products out there, but one I am fond of and have worked with at some shows is Acoustic Innovations. They are American Made products, great people to work with, and have very visually appealing products. Much of what they do is theater oriented and they have an incredible client list that they can't publicly disclose.
