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

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!

After reading reviews and instructions here's my thoughts on buying this: - UNPACKING: be patient, it's foam not an inflatable. I opened them up (carefully separating by hand) and soaked in warm water for about 30 mins, then hand wrung them out to the best of my strength. Left them in a room to dry for a couple days (It lined up with my work schedule so I didn't mind). At the end they generally opened up without deformation to almost full size - it would be impressive if foam ever FULLY re-expanded so I'm happy with the results. - PASS - MOUNTING: cut some cardboard + glue gun to the foam and then command strips to attach to wall. Interestingly, the foam sticks to the cardboard np but the command strips don't like my wall. - PASS on adhesion - ABSORBENCY: audibly no dramatic difference (12 installed across ceiling bulkhead on one wall..) after running a room resonance measurement test however, decay time in the room reduced on the results - PASS - VALUE: I bought it for $30 somehow. Anymore and it may not have been worth it - PASS Overall, I was waiting for restock so I can buy more to fill the room! - PASS

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 libre vienen 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 purchased this product in order to reduce ambient noise inside of my room for production. This foam noise reducer is sturdy and really stong. I just used a slim strip of two sided tape and it has held up relatively well so far. What I really enjoy is that ublike other foams, once you open right of the bag, it immediately opens up to the normal size. There are other products that last up to two days to retain their normal size. I would definitely recomend this product and will definitely buy again from the same manufacturer.

Nula densidad, mal diseño, no cambia los modos de graves en absoluto.
