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.

Bought them to diffuse the back wave of a pair of electrostatic speakers. The speakers are placed 4ft from the front wall. The panels do not have a flat area to place the 3M tape, therefore it went in the corner creases and close to the center. Once installed, I used various songs to test the sound and noticed a difference, more detail at the expense of a little bit of imaging. For the price, I understand they are a bargain.

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

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.

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

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.

I really like the look of these panels, and you get quite a few for the money. But I'm not sure how much of an impact they will have in the small room I'm in. I bought some larger ones a few months ago that look similar but they have a backing and they have some mass to them. So I'm not sure these being just a plastic shell, if they should be filled or leave as is to absorb some of the sound waves. I bought them more for the looks but I don't need them to vibrate at certain frequencies! I will have to update this review after researching more and putting them up. Open to suggestions
