A small DIY project. Although as it turns out it was quite time consuming but fun! A more detailed description on how to make the absorber can be found here
First paint it all white.

I know this is a really old post, but I thought I’d stop by and say this is a great idea. Super easy and fairly inexpensive but most of all they look great.
In your room since it is so narrow I’d put them ear level and have a few behind you as well.
I can’t see the entire room from these pictures but I would think it is a better to move your set up to the back wall, to the left 90 degrees.
A big frame or two hung above the listening position a foot from the ceiling makes a huge difference.
