Sonic Acoustics12 Pack Acoustic Foam Panels 7" X 7" X 12" Sound Absorbing Panel, Bass Trap Studio Foam, Corner Block Finish, Sound Panels Soundproof Sound Insulation Absorbing

This stuff is the best! I used it in the entire space and holy crap I should’ve bought it a long time ago. Easy to put up and makes the space look and sound more professional. If you’re looking for cost effective and functionality this foam is it! 10/10

Ignore the reviews of folks saying they arrived flat; they're compressed, vacuum sealed for easy shipping .. of course they arrived flat! I bought these a year prior and just got to opening them up for use. Bought a 12pk of pyramid pattern and it arrived in a single vacuum sealed package. The inner pack had two vacuum sealed packs containing 6 compressed panels. I tried both methods to revive the foam and both worked, with some notes...If you've never worked with foam before, MOST foam products ship to you flat packed like these did. The leave out and let them rise method works best in a room that remains warm (between 65-75°F) with air flow. Sometimes the panels need more than 48 hours to fluff up, especially if they've been packed for awhile.Of the two methods, the soak and dry method worked best and fastest! A few tips:1. USE HOT WATER. Get the water as hot as you can safely handle and soak the panels one at a time in a sink. Don't drop and flood them... hold them up and soak them under the faucet. If you have a hose you can use, even better. Soak the whole panel. If any edges still look thin or dry, use your fingernails and scratch the edge of the panel. As you scratch it you'll release the pressed edges. I promise they're not sealed or cut wrong. It may take a little effort, but they're fine. Make sure to really wringe them out before throwing them in the dryer. Use MEDIUM HEAT in the dryer for 20 minutes. If they're still damp, throw them in again for 10 minutes.Of the 12 panels, all 12 fluffed up fully however I did take the air fluffed panels and soak/dry them for fullness. These worked GREAT! Sound dampening in a recording corner for half the price!

We bought these as a replacement for a set that wasn’t very good. These were much bigger. Only downside is that they don’t come with adhesive. What they suggest is a spray on, but would want to use that because it would make a nightmare for removal lol. 3M has not proven to be useful either, because 2 have already fallen. The ones in the photo are being held up with tacks, which works but can look ‘tacky’ 😂 if you’re worried about aesthetics.

Not on the thick side, seal was perfect but quality control seems to be the issue with these.Update: I followed method 1, dipped I all of then in a sink with water. Wrung them out and put them in dryer for 25 min in low and all of then opened up nicely. As another reviewer said, these need some patience.

None of these line up. All different sizes. If you don't mind them looking ugly in your studio, then they'll probably work for you. But these are going right in every day view in a radio station. Not gonna happen. In the pics I've attached you can see that these are flush in the corner, and they aren't even close to lining up. Waste of time and money. Because it's too much trouble to return them.

these come vacuum packed in a big plastic bag (no box). Only 4/12 properly expanded and look nice, even after waiting 24-48 hours AND submerging in water etc. Theres some sort of film/spray on them that keeps certain parts from properly expanding, looks horrible.The ones that DID properly expand are pretty nice. They just need to stop using this packaging method lol.Also these aren't symmetrical, from the corner its 6.5 to one side and 7.25 to the other side.EDIT: They took over a week to fully dry out, all the while the cats where very confused about them. Several still have really bad looking patches that didn't expand at all. If you want a cheap solution and dont care about time/looks, this is it.

I wound up ordering 4 dozen of these. Ended up having to soak them in the tub for like 15 minutes to get them to separate and fluff out, which was pretty cool. They're rather durable, but if you do have to soak them, GENTLY wring them out, then let them sit in a fairly warm room in front of a fan for about 24 hours. The instructions suggest that you can put them in the dryer for about 15-20 minutes. I would NOT recommend this. I did this with the first few and noticed that due to the traps being wet, they tend to grip the back wall of the dryer and get caught in between the back wall, and the tumble bars inside the dryer, as it is spinning, which ultimately causes tears in the edges, and chunks missing off of the baffles. I saw that and immediately took them out of the dryer. Air-drying with a fan takes more time, but there is no damage to the product.These traps are very good quality and design for the money! I would recommend them to anyone trying to create a Studio space, vocal booth, or any space where low end is reflective. They make a huge difference! I will be ordering again!

Thicker then expected

me fui con la finta, pense que serían más grandes ya que he visto este mismo tipo de trampas para bajos en amazon y anteriormente he comprado por aquí y por mercado librevienen muy bien empacadas, pero al seguir las instrucciones que dicen que hay que mojarlos y exprimirlos y después meter a la secadora, se dañaron todos los paneles. No creo que les impida cumplir con su funcion, pero es algo que no me esperaba. Al exprimirlos, con mucho cuidado, se rasgaron varios de los paneles de las orillas y al sacarlos de la secadora, había muchos pedacitos que se desprendieron al estar dando vueltas.En general, es un buen producto pero me parece que por el mismo precio se pueden conseguir paneles más grandes

I bought 2 packs of 24 panels (48 total) and didn't have an issue with a single panel. I followed the instructions included (soaking the panels, wringing them out and drying them) then stuck them to the wall with the recommended 3M Vhb double sided sticky tape. Not a single issue along the way, everything blew up to the proper size and stuck to the wall exactly as it should. I will likely still need a few more to complete the room and will definitely be purchasing more of there particular foam tiles. You really can't go wrong. They work exactly as intended too, really killed the reverb in the room, super happy with this purchase 🤘

Muy buen producto. Sí son los 5cms de espesor. Por el precio es algo correcto. No sé siente un material tan frágil y viene muy bien empacado. Sigue las instrucciones para que los paneles lleguen a su tamaño completo.

Overall pretty good but 3 out of the 12 panels didn’t quite expand to the shape they were meant to.

They are OK but from a look point of view they look very modest and more with a paper look feel.
