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.

got pyramid foam 6 - 2x4'. I have 2 12' subwoofers along with 4 tower speakers in a 7.2 surround sound that needed muting of secondary and thereafter sound bouncing. These worked very well. I didn't want to go "overboard" with tons & tons of sound muting material (completely) messing up the charm & décor of the room hence a somewhat difficult task
Love it

I dont need this material for acoustical reasons but rather for its texture, Im a designer and wanting to make a cool pattern on a wall in one of my projects. I already received the large panels and loving it.
Great experience - I ordered $450 of the 2" pyramid acoustic foam in several sizes and colors. Order shipped quickly, and came packed VERY tight in one heavy package the size of a microwave. Upon unpacking, the foam fully retained its original shape withi
