8 Pack - Bass Traps Acoustic Foam Corner, 8''x8''x12'' Black Bass Traps Corner Studio Foam, High Density and Fire-Proof Acoustic Panels Recording Studio Acoustical Treatments

These fit perfectly in my corners and are very thick and durable. They pair really well with my acoustic foam panels. Since they don’t come with adhesive, (you’ll need your own) but once you have it, you just slide them into the corner and they’re good to go. They recommend letting them puff up for 24–48 hours, but mine were fully expanded in less than 24 hours. Great product and well worth the price.

I didn't actually get them for and kind of acoustic purposes, just to fill some gaps along the ceiling in my sketchy homemade office. But they block dust and make it less noisy.

I bought these as an inexpensive experiment to see if I could tame the fatiguing corner reflections behind my tower speakers at higher volumes. They arrived in a flat pack and I allowed 48 hours for them to expand, then installed with 3M double stick tape. I had to assure my wife that they were indeed an experiment because they are ugly. They are dimensionally correct and installed precisely. These combined with my Gaia iii Neo iso feet have done the trick. The corners are almost too quiet. Now I need to decide. Do I design a frame and cover them with fabric or go with an expensive set of corner traps. Buy with confidence if you are looking for an effective solution and don’t care how they look.

Pedi 3 paquetes de estas trampas de graves para utilizarse en la adecuación de una sala que se le dara variedad de usos, grabación de video conferencias, podcast entre todo lo que quieras imaginarte. Debo decir que funcionan increible para este espacio, me llegaron supremamente comprimidas, pero luego de abrirlas y dejarlas un rato empezaron a tomar su forma sin necesidad de sumergirlas en agua, esto fue muy positivo puesto que no teniamos tiempo de esperar a que se secasen para ir a instalarlas. Su funcionamiento es el correcto, atrapan ese esceso de grabes que pueden generarse en salas como estas debido a su tamaño, esta es no es una sala de estudio de grabación de audio, en la que se necesite que su acustica sea estratosfericamente buena, por eso no me atrevo a decir que son lo mejor para estudios de grabación porque se que existen otras espumas con mayor capacidad de respuesta para las frecuencias graves. Pero si estas empezando y quieres solucionar la acustica de tu proyecto estas seran una buena opción para ti!!

They work great but they need to work on the cut so the line up better

So far these are working great

Pieces are not symmetrical. They inflate to 8 inches on one side and 6 inches on the other.. you can put two of them together to make an 8 inch piece, but then you’re getting half as many. Avoid this at all costs. Additionally, as you can see on the picture, even if the sizes were equal, the “fingers” are not centered and are slanted to one side so equal sound absorption from both angles would not be a thing

Great. Exactly what I needed so change the sound of the room. Definitely provides enough absorption that only the low end still travels through which was exactly what I was expecting. Did not come with any adhesive strips so I ended up using picture hanging nails which worked just fine. This is a temporary space and some what of an experiment until I build an actual wooden isolated booth within a room.

Works well but took a week for the strong smell to abate.

Calidad buenísima. Densidad adecuada. Excelente producto!

Excelente producto.

basic acoustic foam, don’t expect an enormous difference, but it does help the low end

1 had a curl and cut defect vertical and one would not align with any others . Poor quality control and would not purchase again.
