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

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

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 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!

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

PITA to apply. Finally said the heck with it and used my staple gun. These do make an acoustical difference. I'd say these are worth the price and the hassle of installation. Theater room is discernably quieter.
