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.

The image we see in a mirror is virtual not real.

Surely, hearing a central image in stereo is a trick of the mind. The ears detect two equal signals in phase coming from the loudspeakers, but we interpret them as a single sound coming from a point midway between the speakers.

I’ve always been more concerned about the internal loudspeaker of the TV resonating in sympathy with the sound in the room. My acoustic guitar does this when not in use so I dampen the strings with a soft cloth. Removing the surround loudspeakers from my listening room improved stereo performance.

Unless the stereo loudspeakers are toed in sharply and have front baffles close to the front wall or the TV projects out a long way, I can’t see how mid range and high frequencies that might cause problems could directly reach the screen.

Thanks for the advice. I’ll give covering the TV a shot. Also will pay more attention to guitar - maybe putting the cloth over the sound hole will help. I suppose I could move it to another room.
