TroyStudio Acoustic Sound Diffuser Panels, 19.7 X 19.7 X 1 inches 12 Pcs Black PVC Plastic 3D Wall Panel, Recording Studio Acoustical Treatment Diffusion panel, Art Decorative Ceiling Tiles

Great build quality and improves the sound. The mid range sounds real clean and crisp and the bass tighten a little bit. Overall very happy with the sound diffusers and the sound quality. Really opened up the room to make it very lively. Sticking these things to the wall has been a challenge as they falling off. I am using blue tac and it goes on easy however I would recommend to use a lot and thick patches. At first I put them on only the four corners and after a while they would slide down. I then put in every corner I could and all over the middle. I used thick pieces and then really pressed it against the wall to stick. I hope they will stick this time if not I’ll probably use 3M double sided tape. That’s the only problem is how to mount them however when you see the design it’s easy to see why it can be a challenge. Looks wise it’s pretty nice to and gives the room a little artistic flair. The wife liked it so I got the wife approval.

It can be used as decorative for my audio room beside the diffuser function, i put at the wall and ceiling ao the backGood, it is very light, so it is easy to installThank you

Bought them for my husband’s editing space and they gave a really nice touch to the room. He put a light projector underneath on the table so when he turns the lights on the room looks amazing with this panels.The only “negative “ thing I would say is that, you truly have to make sure you double tape it with double sided tape and hold it for a few seconds because if you don’t use a strong tape…it will fall! They’re not heavy but not lightweight if it makes sense? So yeah. I would purchase again to make the design bigger since like I side. It looks really nice in our room and you can use them for a lot of things.

It looks good, sounds good and I think is worth the cost. My only complaint is that it has no means to secure it to a wall. Even with adding my own adhesive strips there is very little flat space to adhere them to.

I ended up designing/building a custom hanging diffuser/space coupler with an integrated bass trap behind it (complicated design/build) by using 3 (three) of these on at flat main reflection point between some ceiling coffers I built in my theater. I do a lot of custom woodwork, so I was up to the challenge, but it definitely wasn't easy. These really are more for aesthetics than actual diffusion because they're too shallow to work on a lot of frequencies, but they do look cool, which, if we're being honest is a big part of why people buy these. In addition, being fairly floppy and hollow on the backside with a very short outside lip makes them very hard to mount securely. I used PU construction adhesive on all of the back side valley trenches, but I also attached some wood trim around the outsides of them (on the shallow lip) to feel more secure about hanging them without them rattling loose or sounding hollow. For my use, it would be great if the lip around the edge of these at least protruded out further, so you could really lock them down. Anyway, I ended up painting them with the rest of the diffuser/space coupler, because the black PVC was too reflective of light and looked pretty cheap while unfinished. I'm not sure what I'll do with the other 9 (nine) of these I didn't use because they're really kind of a pain to mount securely while looking decent anywhere. I've got a lot of other custom diffusers/absorbers/traps in my theater, so I wasn't as concerned about actual diffusion performance as I was about aesthetics with these, so I'm ultimately fairly happy overall with them, but you should at least know what you're buying and how hard they are to work with.

I used these in my home theater /music room. The acoustic design of my room has absorption panels on side walls with 3 diffuser panels on back wall. I enclosed the panels for the rear in a frame and in the front the diffusers are behind my theater screen which is acoustically transparent. The room definitely opened up and the soundstage expanded. Mid and highs are especially nice! The cloth is speaker cloth that is acoustically transparent. I will say the diffuser panels did change the graphs my HT atmos receiver’s room calibration software generated. Not in a negative way. The sound panels are 3” thick rock wool. Pics show how I built and installed.

As advertised! Recommends seller

Been about a year and with the use of command strips they still stay solid on my wall :)
