The argument I've heard in favor of full rounds is that you can rotate them to adjust the amount of the diffussor covering that is oriented towards the listener. I assume the Frescoes are absorbtive on one side, and diffusive on the other?
Tube Traps and other room treatments
Interested in hearing what other "Audiogoners" are using for room treatments. Particularly interested in experience people may have in trying to treat a room to achieve good results for both music and home theater. I've just added 4 ASC Tower Cube Traps (60" high), and use two 9" full round tube traps in front of the monitor when listening to music. I've read much of the technical literature about tube traps and other treatments, but would like to hear feedback about experiences in real home listening rooms.
