About 3 years ago I built or attempted to build a theater. Now I have decided to upgrade my theater. Unfortunately my room is not the best room for a home theater, but it is what it is. I am looking for suggestions and ideas. Of course, my budget is very low. I plan on replacing the side surrounds with in wall surrounds and would like to install some rear speakers. Currently it is a Boston acoustics 5.1 HTIB.
Forgot to add some pictures. Here are pics of what I am working with. As you can see some of the walls are angled part way up. My plans would be to add some columns below the angled wall and add some wainscoting with acoustics panels incorporated in the design.
