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.

@spenav I see you are on a path with the dust cover.  Too bad camo wasn’t available in cotton.  Will be interesting to hear about how that works out.  Looks like your speakers are well into the room and your TV is well back of your speakers.  Not sure whether that reduces the impact of the flat screen on sound or just changes it.  Having the space from the back wall likely allows you to get some good depth in the soundstage which is great.  

My system is all on the wall in a purpose built AV/audio room.  I realize I am giving up soundstage depth but other aspects of reproduced sound are more important to me and I just like the clean layout.  On my TV I am using a medium weight wool blanket to cover 65” TV when listening to music.  It is not the thickest wool blanket I have tried, but it sounds the best. Center fill locks in, instrument placement improves both laterally and vertically, and there is much less glare in treble at volume.  The value of having the blanket in place has increased directly with improvements in analog and digital front ends and cables.  With the blanket over the TV I can get to recording studio volumes now and impact without noticeable distortion, which is fun in short bursts.  The blanket is bigger than the monitor so I drape it longways over the top and roll the overhang on each edge and stuff the rolls behind the TV to flatten the front face and to block sound from getting behind it.  I do not recommend lightweight fleece blankets as that did not improve sound nearly as much.  Heavy wool blankets, heavy cotton blankets and cotton towels all sounded worse, some worse than the TV alone.

As for the “where it belongs” statement, I have definite opinions and agree with many of the comments here that there is no dogma on this topic.  Call me old-fashioned but TVs in the living room are red card foul.  My opinion and a very subjective one.

For years in previous homes we had our two-channel sound system in our living room and our TV/home theater in a separate small bedroom space.  When we rescued and moved the main floor of an old house to a new lot I intended to have a two-channel system in the living room and a surround/two channel hybrid system for watching TV, movies and serious listening sessions in a new purpose built basement room described in the link above.  The acoustics in the purpose built room are very good.  In our 100 year old plaster walled, multi windowed, tile, wood and brick fireplaced living room, not so much.  So much not good that I abandoned having a decent system there in favor of a good Bluetooth speaker for background music, audio books and news - all serious listening is in the purpose room downstairs.

As for center channels and multi-speaker music listening versus serious two channel set ups, the better my sources the more I appreciate two-channel versus multi-channel reproduction with DSP.  But sometimes, listening to something like Miles Davis “Tribute to Jack Johnson” with 13 drivers around the room and 1,000 watts on tap is a revelation.  In all things HiFi, YMMV.

@knownothing. Well, you’re better off than I 😄. I see that you have your own room. Your system looks pretty nice. I would think that your soundstage depth be ok since your speakers were designed to be wall mounted. Don’t be afraid of using DSP to make things better. The technology is quite mature nowadays. Your cover looks quite cool. I was shooting for something similar but all I could find was black cotton. I plan on putting a thick backing to the front to improve the acoustics. I bought some cotton batting and some medium-loft batting (cheaper at Hobby Lobby) yesterday and will put them together as soon as I receive the cover (taking way too long). I will give my honest opinion as soon as I get that project going. If that doesn’t work as expected, I will put something more substantive together and share the blueprint with the group. I appreciate your input. 

I used some cheap diffusers and absorber off Amazon and put them on foam board in a frame so it was light weight to put up for serious listening. Eliminates glare and adds depth. I might build something automated some day. Liked it so much I put one over the fireplace on a secondary system. I didn’t like just the diffusion or just absorbers.

I used to have some Gik panels mounted on some aluminum planks, but they were too heavy to move.

Doesn’t your LG OLED have built-in works of art to make it look like a picture frame?

I think these OLEDs are brilliant and the very thin panels have almost no effect on sound transmission or reflections.  Sony’s version fires its main speaker through the panel.

I can see that my old Pioneer plasma may have some sonic effect, because it is glass faced and so thick and heavy.  But really, how much sound do most speakers manage to spray out sideways?  Or is the TV panel complicit in re-reflecting sound waves bounced back off the wall behind the listener?

I am thinking about (real) cinemas seating hundreds in a rectangular space, some well to the sides, where a centre speaker behind a fabric screen does make sense for some of the people some of the time.
