Capable of soundproofing any size room, 3 inch pyramid foam is fantastic all-around sound absorbing foam. When used in conjunction with corner bass absorbers and male/female broadband absorbers, it performs even better.

Pyramid vs. Wedge Absorption
To create the pyramid style, this foam must pass through our machine twice, resulting in a higher cost than the wedge for a more visually pleasing product. With less overall mass than our wedge foam, it provides about 76 percent as much absorption than the wedge, but has a better diffusion rate.

Great as always

This is my second purchase from The Foam Factory and they do not disappoint. Top notch quality, fast delivery and overall friendly service. The 2" pyramid was a perfect fit for my studio. Will never hesitate to buy more when the need arises.
Received 2" not 3" .

I received the thinner 2" pyramid when my order stated 3". I overpaid, and am not very happy about this.
