Sorry if I was not clear. I was replying to your question: "Can you spell absorption?"
It was supposed to be a joke. :)
Regarding your woolen rug on the wall... I'd have to look it up, but I think you're getting most of your absorption between about 125/200 Hz and about 500 Hz. I'm not sure if that's what you want. Check out "Master Handbook of Acoustics" and "Acoustical Designing In Architecture". They both have very good guidelines for absorbers. Also, the ASTM has a lot of this kind of info. Lastly, for the cost of a not extremely expensive turntable/cartridge, you can get a real acoustician to come in to evaluate your room.

If I had extra coin? I'd be tempted to get an ISF guy here to do a TV tuneup.
The new generation of OLED sets are nothing short of Spectacular. The new '7' series are supposed to be better. I have a 2016 'B6' which blows me away. No 3D, which makes me dizzy with those horrible glasses and only OK source material.
I'd make 2'x4' panels using OC703 or similar in 2" thickness. 2x framing and a couple cross braces would provide anti-racking while choice of 'grill cloth' for acoustic transparency and appearance. But I would probably make DIFFUSORS first,
Too much is never enough
