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.

Ah, but you used the term to strongly imply two-channel and you also imply there is only one format and that it was designed by "the inventor" rather than evolved over time.

My personal opinion is that stereophonic was designed to be sufficient for the reproduction of live music. ...  When done correctly, two speakers can put you right in the venue where the performance is recorded

Morten Lindberg, I think correctly, says audio is an illusion.  Somehow our ear / brain system builds up a ’picture’ and basically it can be fooled into ’seeing’ a soundstage just as the eye / brain system is fooled into seeing moving images.

I would encourage you to go online to 2l.no and buy a copy of Reflections.  You probably already have a Blu-ray player to feed your Dolby 9.4.4 setup.

I think single apparent source speakers improve the illusion because they don’t muddy the waters with interference effects from different pathlengths, and they don’t produce incoherent reflections from walls, floors, ceilings and maybe TVs.  The Duntech example I gave is the other extreme, where the multiple, separate drivers interfere quite severely between themselves.

I could only find the ClairAudient 1+1 V5 on the web and in its blurb was amused to discover that it is the most unique (there are no degrees of uniqueness, it either is or it isn’t) and that it eliminates the need for desperate drivers (plenty of those where I live)

The 1+1 V5 Personal Reference Monitors are the most unique small footprint loudspeaker in the world. They feature a highly refined proprietary wideband driver eliminating the need for desperate drivers

I see it actually has two full-range drivers in a bipole arrangement, and passive radiators.  You are worried that your plasma TV needs damping but passive radiators are OK?  By the way, if I did want a centre channel, the Audience might well be ideal!

@richardbrand.

Your first sentence is correct. When audiophiles talk about stereo, they are strictly referring to the two front channels. Yes, stereo has not evolved over time. The format was invented and patented by an inventor. My best stereo recordings are from the 50’s and 60’s. Stereo is not in your gear, it is in your recording. I am using two mono amplifiers to play stereo and if something is wrong with them, I use two channels of my multichannel home theater amplifier. The term has been used loosely for the most part. 
Stereo is an illusion just like seeing your image in a mirror is an illusion. There is not two you in the room but the image is real. It is however happening in the optical domain just like a phantom stereo center image happens in the acoustical domain. It’s not a mind trick per se, it’s real but in the acoustical domain. 
I intuitively feel that the big glass surface of my plasma TV is affecting the sound of my stereo system. I should be able to assess this objectively in a couple of days. It’s in the acoustic domain and I don’t have the tools to measure it accurately. Stay tuned.

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.

@newton_john
You are correct. My choice of words was incorrect. I hope my meaning wasn’t lost in translation. My point is that the image is not a magic trick but something that can be explained, manipulated and repeated. In other words, it’s physics not voodoo. 

I asked Google Gemini for treatment options. One of the options was using sound absorption to the left and right, behind and below the wall hanging TV.  I used 24x48x2 panels (thicker panels would not fit behind TV) extending behind by 3” & below by 5”. Gemini claims this largely mitigates the problem. 
It recommends experimenting with speaker distance (mine are 30” out) from rear wall and ensuring there is no resonance from the TV & mount. Since the bottom of the TV rests on the absorption panels, that should help mitigate any resonance. 
Lastly, it states ’if you want to go the extra mile’ try placing thin removable panels or dense velvet/felt over TV during critical listening. Hope this helps.
