Flatscreen between speakers


Has anyone found a solution to cancel or at least improve the acoustic glare caused by a flatscreen tv on the wall behind the speakers? I don’t have a dedicated room and have to share the room with my home theater setup. I have thought of using an appropriate curtain and treat the tv as if it was a window. I am also considering light 3D printed panels that I can temporarily hung when listening to music and take down when watching TV with the wife. 
I tried hanging a couple of thick towels on it to see if there would be any improvement and the answer is yes. The center image is more solid and a little deeper. Nothing drastic but if I could squeeze anything positive, why not. Please let me know if you have confronted this issue in the past and whether you were able to solve it. Thanks.

Good suggestions guys. I will put something together and let you all know how it turns out. @wsrrsw, can’t do that. The wife needs her TV. @erik_squires, yes I am considering heavy drapes and treating it as if it was a window. I will try to come up with an elegant solution that is not too expensive otherwise, where is the fun in doing it if I can just throw money at it, right? @gdaddy1, I am seriously thinking of wool but it’s very expensive but it’s healthier than other materials as far our lungs are concerned. 

I ordered a couple of fabric covered 4" acoustic panels from ATS.  No frame, but the panel is stable enough to stand upright so it is easy to move.  In my case my TV is on the long side of my room, so I use panels for 1st reflection, but the principle would be the same (portable solution).

Migrate to a drop down screen and projector when the TV is at end of life.  Put a diffuser on the wall where the flat screen was.  +25 horse power.
