Dark Grey convuluted foam

Ozzy where would you put the foam? The TV between your speakers would be the most apparent and logical spot for treatment. I would not use any type of foam product...they suckout to much energy and life and dynamics. The most broadly linear and least detrimental is natural long hair wool. You could make sound panels framed of 1 by 2's and covered in a fabric of choice and then hung on the wall or in front of your TV when listening to music.. Easy to move the panels about, very effective and lightweight. I have a few bags of long hair wool unused from several acoustic projects if your interested. Tom

The problem response area has to measure as the inverse to the foams absorption efficiency
over a pre measured frequency. If not you will have a suckout and lotsa deep dark lifeless soundstage. Try that balancing act on your next year off. Most room issues can be dealt with proper geometry and the use of natural materials. Solutions and products as mentioned that are not normally advertised, reviewed, shipped, sold or suggested by retailers of any type.

Recently there have been rooms described where instead of the vendor/designer suggesting solutions at the outset of constuction,the expert has sold at the end a truck load of foam and fiberglass band-aids as the cure. I feel this approach is is an error in judgement and a dis-service to both the customers ears and bank account.
