2 inch pyramid foam is effective against standing waves and flutter echoes in most small-to-medium sized rooms like vocal booths, control rooms and studios. It also functions as a full-frequency bandwidth absorber for any size room when used in conjunction with corner bass absorbers and male/female broadband absorbers.

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.
