23.62" X 11.81" X 2" Fiberglass Wall Panel, 4 Pack Acoustic Panels, Acoustic Panels Sound Absorbing for Office, Studio, Home Theatre - Heather Grey

Perfect for managing sound!

Makes the acoustics sound better and looks top notch in my opinion. I Love! 💪🏼

I liked the price on these panels more than anything, and for what its worth it. they surve their purpose. However the material is pulled so tight around the corners the material ripped. Also they are very hard to hang unless you plan on drilling a ton of holes in your walls. The back side has built in plastic round standoffs that make it almost impossible to use with double sided tape. They want you to use the heavens metal brackets and screws it comes with to mount. That being said I still used the brackets with a ton of double-sidded tape which comes at an extra time and expensive cost premium. These are more rigid foam fiberglass style, and in my opinion rockwool mineral wool is a little better. Overall 4 star and would buy again for the price.

Bought grey and linen panels in different sizes. The color matches my wall and texture feels good. Initially has some issue with the linen panels, but seller contacted me and offered solution. Over all satisfied.

These panels are well-made and look nice on the wall (better than my homemade ones, for sure). However, they are too small and light to provide significant sound absorption. They only measure 23" x 11", and weigh under a pound each. You would need 8 of these to come close to matching a single 2' x 4' panel. A typical room would need dozens of them to get significant absorption. Even then, they won't do a lot for bass frequencies as they simply aren't dense enough. For spot treating some small areas, they are fine. I do wish they were more of a pure white to match my walls, but that would also show dirt more, so it's a tradeoff. I did find that a few of them had some stains or odd repair-like features on the back (see pics) but this is not a big deal since you never see the backside once installed. Speaking of installation, I found the liner on the adhesive to be a bit difficult to remove. It wouldn't have mattered much if it was one liner per panel, but each panel has 6 separate adhesive strips. It took 1-2 minutes per panel to get the adhesive off, but other than that, installation is simple and the adhesive sticks to a painted gypsum board wall well.

Installed 4 of these, great fit and finish, the adhesive is also very grippy. No smells from this

Website description says use self adhesive. No mounting point on the back. Box has printing on the outside that says use "super glue". Come on. Who would super glue something to their wall? Returning

Panels were warped. Thought about using them anyway, but decided to return and get thicker, better made, reputable USA made panels. Much happier.
