As you know most acoustic treatments don't blend into a living area. The one exception that I have seen is the method used by Richard Hardesty. When you step into his living room you have know idea that it has had any acoustic treatment done. It simply looks like he has expensive cloth walpaper installed. Not only is it rich and attractive, it works. I have yet to hear a better room in a home.
I beleive that there is a description in his second journal, which is free to download at his audioperfectionist website. Since you live in Los Angeles, call him up and see if you can't arrange a meeting with him to see and hear for yourself.
