Wooden blinds vs cellular shades for acoustics

I have used partially open wood blinds for years and this is a good start, but I have cellular shades over the sliding glass door and this is a better midbass/bass trap and allows for high dB listening without a standing wave. In addition, I have a coffee table in front of the couch, between me and the speakers and I covered the bottom of the table with foam egg crate and this is another great bass trap, and is not visible. I use this under all furniture I can get to until the bottom end is tame. Wall tapestry is another good tweak if needed. Too much though and the bass will be thin, pinched and dry overall. Tuning a room is the art to fabulous sound....Jallen

Being a natural material, wood makes a good insulator and acoustic diffuser. Here are some more interesting tips about wooden blinds http://www.articlesnatch.com/Article/The-Ins-And-Outs-of-Wooden-Blinds/1084597 . Hope this helps

Anyone else have any experiences they want to share with adding Dynamat, Marigo dots or something similar to windows or glass surfaces in their listening rooms?

Thanks
