Greetings to the community. At the Vienna High End show, there was a presentation of a flat TV acoustic panel.
I thought it might be useful for many audiophiles.
It is very easy to mount and remove, consists of three elements, is very lightweight, and provides effective acoustic treatment.
What is the community's opinion? More details about the product can be found at:

Not so sure about the "sleek modern design; looks great" part. I want to hang my tools on it. A set of heavy drapes with vallance would do the job and add some theatrical flair should you go with electric retraction.
 
I have a secondary 2-channel system and years back bought some Owens Corning 703 which came with hard plastic corners and microfiber covering of the color of your choice. I don't use the system tons but it helps. The system heart consists of a Lumin M1, where I have an old Oppo 103D going into a modded Carver C-9 Sonic Hologram Generator into the analog input of the M1. I'm sure there are better things but it's easy and quick for me and I don't use the system much. This is another example - https://www.ikea.com/us/en/cat/acoustic-panels-46077/Back up 1- 2026.jpg
 
Here's my challenge: I would need something that somehow hangs from or attaches to a 77" screen that is mounted high on the wall and tilted downward.
 
GIK and others make combined absorber/diffuser panels that are one piece and easy to mount. I think treating the TV is a good first step. Looking at the room as a whole entity is a better approach. It’s easy to over absorb HF frequencies, under absorb bass, and not have enough diffusion.

I seldomly see appropriately treated rooms, even ones with $1M systems in them. My rooms are no exception BTW, so this is a little of the pot calling the kettle black. :)

I incorporated acoustics into the design of the new theater. We’ll see how that comes out.
 
Interesting device. I do understand room treatment and some of the issues that @W9TR describes. I have generally measured my rooms with REW and attempted to treat accordingly.

I have a very thin TV mounted on my wall, with no space behind it. I’m not sure that the surface of my TV reflects sound any differently than the flat surface of my wall.

I will be doing another comprehensive room measurement/analysis this fall. Just for grins I’ll try a measurement with some sort of blanket over the TV. I suspect that those results will be similar to placing treatments on the wall behind each speaker.
 
A good idea and I'm surprised no one has done that before now.

Like Phil I use a couple of Corning 703 panels but without the frame. I just move them when wanting to use the TV.

To Bones comment. Since my panels are easy to move around I did play with placement. My TV is on the wall in back of my speakers. Not directly in back, more like between the speakers to the back. Anyway I found in front of the TV worked better than corners or other rear wall placement. Whether that is due to the TV or location I can't say, the TV was there first.

Under the TV is a stand that holds the center channel and the panels sit on that to block the screen. The stand could be another reason my placement sounded more crucial.

I do have a few more panels placed around the room.
 
In my 2.0 system, the speaker baffles are 4 feet from the back wall, and 9-10 feet apart. I do have an equipment rack under my TV (see my entry in the DIY section).

My current treatments include stacked GIK corner absorbers, and one 2x4 (6”) baffle on one of the back side walls. These treatments date back to my 9.5x14 room. Interesting that they work better on the 50hz boom in this room, vs the 40hz boom in my old room. Current sidewall treatment is diffractive with an IKEA Kallax unit on each side, on the legs sold to go with them. I’ll be checking one day to see if I need additional absorption in the first and second reflection spots. All waiting for final speaker positioning, and listening location.

As discussed here, further treatment of the wall/TV will be considered. I do use the TV to display album art, sent from Roon, during playback.
