New Level Column Acoustic Wedge Studio Foam Corner Block Finish Corner Wall in Studios or Home Theater (8 Pack)

El articulo es bueno pero no trae nada para pegarlo por lo que me toco comprar cintas doble cara para poderlos adherir a la superficie, el nivel de absorción creo que lo normal.

I do not have the needed equipment to test what, if any, difference in acoustics this product may have made to my listening environment. I can confirm they are the size advertised, cut precisely and the pieces I received were all uniform with no anomalies. I do wonder if I can dye the pieces with diluted interior wall paint, not only to match my wall color but to increase the density of product?

These definitely have a smell to them. I had to let the product air out for several days due to the smell. They do not have any sort of adhesive. I chose to use command poster strips. Unfortunately you have to place multiple strips to keep them from moving. They reduce sound effectively. They were used as my bedroom echoed horribly which made the sound louder. They also reduce noise from the kitchenette on the other side of the wall. They are effective, however having their own adhesive backing would be a major improvement.

Well formed/cut; shipped without compressing the foam. Affordably priced. I'm satisfied with them.

This is NOT acoustic foam, this is just a junk piece of very light foam that does strictly nothing.As a test I put one ear next to a very serious foam panel and the other in front of a speaker. Then I placed the foam in front of that ear to see how much of the sound it was taking off. I then compared it to one sheet of paper and the foam was slightly better. Then I compared it to 2 sheets of paper together and it was the same.In other words, this form is an illusion. The only use I can see for it is if you have clients coming in your studio and want to make it look acoustically treated just to appear more professional.

Just what I needed for sound treatment in a tight spot. A little spray adhesive and they are there for good. Price is right as well.. These can be used in a number of circumstances.

I will buy from this seller again in the future. Super price and fast delivery.

The are bass traps. You can definitely say that.They seem to work well. I use them on the wall corners and on the ceiling corners.I would buy them again.
