4 Pack Bass Traps for Ceiling Corner 16.5" Triangle 12" Depth Triangular Pyramid Acoustic Foam Bass Trap Sound Proofing for Home Studio Booth Low to High Frequency Sound Absorption Foam

Noticeable improvement after installing. Room no longer boomy

These things are very high quality dense foam. They almost completely removed the echo in our drum room

This is a great way to acoustically treat your theater or any space that needs help with echo and sound bouncing off different surfaces. They are made of a very dense foam material. These were the first acoustic treatments that I put up. I did notice a slight improvement as soon as I put them up. Again. These were the fist things I put up in my room. And they were the easiest. They fit in the corners nice and utilize every space available to add more treatments if necessary. I would have given 5 stars but I feel they need a few more pieces of the double sided tape. One did fall but I added a few more pieces of my double sided tape and they haven’t come down since. I love that they fit perfectly in the upper corners of the room. You really have to look to see mine. The price was definitely worth it. It is a great quality product and super easy to install.

Muy buena calidad

Because they are vacuumed sealed it take days for them to return to its original form, and the form isn't true as I think it should be. And I thought they'd be a big larger. I'm sure they'll work, but I think $50 is over priced for these particular style of corner abatement foams. I think $25 for the 4 pack of these type are more reasonable. There's not even any fasteners that come with it. Apparently they are magic, they're just supposed to float in the corners of the room 🙄 🤷🏻‍♂️

The product arrived damaged. The set up process was a pain, I don’t have much room to soak and dry all 4 of the traps. The foam is CHEAP not worth 50 dollars in any universe. And to top it all off, nothing I did would get it to stick to my walls! I cleaned the area with rubbing alcohol, and used spray adhesive, didn’t work (it just absorbed into the foam). Cleaned the area again and tried double sided adhesive. The fell down in a day. I even tried gorilla tape, the fell off and damaged the paint on my walls. I have no clue how this product has any positive reviews. What a SCAM!

No fault of design, I just didnt read the dimensions. I thought they would be bigger for the price of $30 each. But thats my fault. Decent, dense foam quality. I currently use in the corner of my bed to reduce the bass trap that happens from outside low end noises. It helped a bit with mitigating the moving sound waves.

functionality is good sound reduction is also good build quality is good
