Foroomaco 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 Proof Foam

Absolutely terrible. The units do not expand to size and are not good quality. Do not waste your money

bought these as they were the only thing on the market which suited my needs.Really not worth eht £70 price paid.

davvero un pessimo prodotto, arrivato deformato dalla confezione sotto vuoto non riprende più un aspetto decente

Kleber halten schlecht

Es material de muy baja calidad, llega empacado al vacio, comprimido. Al desempacarlo no se expande solo como otros productos. Se mira horrible, y aun que lo expandas, instalado no se mira como en las fotos del producto.

Absolutely garbage and waste of money. Cheap quality low adhesive foam. Buy real bass traps not these hoping they will work out, they won't.

Great Bass Traps they're pretty Solid thick and heavy. They come vacuumed sealed so out of the box they won't just expand by themselves. FOLLOW THE INSTRUCTIONS, put them in water (Like a bathtub as shown in pictures) squeeze them like a sponge and they'll soak up the water and expand and take form. Lastly throw them in the dryer for about 15 minutes or so or use a heat gun or hair dryer to get em nice and dry. Then use whatever adhesive you deem appropriate as they are pretty heavy I recommend using something strong like Gorilla if these are permanent to the room. Sadly they don't come with any means to stick them which is why I gave them 4 stars. All and all GREAT product highly recommended! 💯👍🏽
