Flat screen between speakers, again.


I know this has been discussed before, but after reading most of the somewhat recent responses to similar questions I still need to pick your collective brains.
To mitigate the TV's impact, I am considering building a panel that would cover the TV when it's not in use. The panel would be a 2.5' x 4.5' diffuser or absorber. Ideally it will hang above the TV when I am watching TV and would lower down to block the TV when I am listening to music.

My question is whether this is a viable solution and, if it is, would I be better served with diffusion or absorption?

@tony1954  Try a test with a sheet of Owens Corning 703 fiberglass board and see what you think.
Perhaps a 5 sided box with absorption on one side and diffusion on the other side that could slip over the tv might work? Just be mindful of the cabling.

Long ago way before the projection screen that mounts on the wall I had a TV. I mean a real vacuum tube TV. As thick as it was wide, which wasn't much, only 32" screen. Yet that was big enough to hear the improvement when covered with a thick blanket. Forget towel, THICK blanket. Think quilt.  

Forget diffuser, too heavy, cumbersome and expensive. What you want is absorption. A nice cheap and light, easy to move around panel.  

The stuff you want is called Owens Corning 703 acoustic panel. I would just get one, 1" thick will be plenty, and wrap it in some open weave (think speaker dust cover) fabric. 

Make something to hang it over the screen when listening, put it on top of the TV when watching. Easy peasy.
