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.

I have a TV as well and was considering these diffusion panels from GR Research.  They are lightweight and could figure a way to easily attach and remove them from the TV with some simple brackets.  At $225 for 4 - 24" x 24" panels seems pretty reasonable.

I have ordered this one on @macg19 recommendation. When I receive it, I will take some measurements and conduct some listening test. I will let you all know if it was worth it. It was cheaper than some other recommendations, like the home theatre curtain by @avanti1960, although they do look better, classier and maybe more functional. I was working on a budget though and didn't want to break the bank, given that the problem is not that big. Stay tune.

"My experience is My Experience. The List includes (but is not limited to) HT and HiFi “things” I have learned to no longer waste time, effort and/or resources on…

Low efficiency speakers, low impedance speakers, subwoofers, encode/decode protocols, extraneous wiring, room reflection issues (proper room treatment is of Primary Importance), screen reflection, multi speaker radiation interaction, digital glare, inadequate digital “sound processing “… I could go on but to what point?

My experience had lead me to organize my audio systems thusly…I have my HT system in the living room (where it belongs) and the 2 channel in a dedicated room (where it belongs). High efficiency, Large Full Range speakers, custom electronics (almost exclusively hand assembled), science guided room treatments and as few wires and connections as possible."

What an arrogant response. "Where it belongs" is your opinion, not a fact.

A big flat surface between your speakers produces an early reflection free zone. This can be good or bad. The reason it could be bad is that too few early reflections can color the sound and skew the imaging worse than more but weaker early reflections. The TV isn't diffusive, so it becomes an early reflection dead zone, making it more important to deal with early reflections from the floor, ceiling, and side walls using combinations of diffusion and absorption. There will be sounds directly from the speaker bouncing off the screen at an angle and then heading toward the opposite side wall, and then bouncing back toward you. Treating those sidewall locations as well as other early reflection points may improve the imaging. 

One thing I do is mount my TV higher than my seated eye position, and then angle the screen down so that it's squared up with my angle of vision toward the center of the screen. I'm not sure what this does in terms of sound quality, but at least it eliminates the parallel surface problem between the screen and the wall behind me.
