4 Pack Acoustic Fiberglass Panels 23.6"x11.8" Sound Absorbing,Charcoal Grey

I was trying to dial in the "sound" (or lack of it) in my new voiceover booth and the acoustic "eggcrate" foam wasn't doing the job and looked dated (a lot of sessions are now done via video so the "look" of a booth is now an important criteria), so I purchased those panels. They installed easily, look great and sound great as well. I put four on each side and they made a huge difference :-)

Panels work great. No smell, arrive assembled you just need to mark the wall using template provided an easy secure mounting. Very happy with the reduction in conversation carryover with my wife’s office on other side of the wall.

My stairwell use to be an echo chamber for every sound inside and outside my house. Hung these panels up and it is noticeably quieter. They also function to balance out the stairwell with my art on the other side. They are very durable and look very nice. The adhesive left something to be desired, so I just super glued picture hangers on the back and hung them that way.

Our clinic has barn doors which look great aesthetically but are not great for sound so we tried these out. I was skeptical they would work but I'm pleasantly surprised. Only complaint is the first few days after putting them on the wall a few would randomly fall off. Definitely recommend letting these acclimate in the room for a day or two before sticking them up. But overall very happy. We bought more for each exam room.

The panels work well and are pretty good quality but the adhesive is quite bad. I stuck 5 of the panels on the wall, all side by side, and within a few days they all fell. After about 10 hours after putting them up, the first panel fell onto one of my monitors breaking it. 2 days later, the other 4 fell at almost the same time. I would still recommend getting these, but just make sure you have another way to mount them to the wall instead of relying purely on the adhesion tape. Also the panels appear to have no mount on the back to screw them in.

Easy to install & they absorb most if not all of the echo & reflection distortion, made a huge difference in my surround system & my system is high quality with a dedicated OSD nero xa 5180 . my system is performing better than ever before with these panels & other foam sound absorption 12×12 panels

Corners fell apart while opening the packages and exposed the very cheap internals. Build quality is horrible otherwise I’m sure they would’ve been fine.

These work great and look great, what more can you ask for? I got three packs of these and wow do they make a difference when listening to my stereo system. I'm very much a believer in room treatment now and these are wifey approved. Enough said.

Overpriced, and at best moderately effective.

Love late night tv. Applied 4 of these panels to my den door and it really cut down on the hallway noise levels. Now everyone is happy!

One year later and still stuck to the wall. Helped reduce the noise around the laundry room..

Excellent quality panels and excellent customer service. These panels definitely help to reduce echoes and reverberation in my home theatre room. I can't say enough about their customer service. I contacted customer service as I was looking for advice on an alternate way to hang these panels. I did not want to permanently stick the panels to the wall. Upon asking, they then explained that they have brackets for these panels. They then proceeded to send me the hangers free of charge. The brackets were pretty straightforward and easy to hang. I couldn't be happier.

Je n’ai pas eu le temps de connaître son efficacité. Les collant n’ont pas tenu et la peinture a arraché.
