Auralex 4" Studiofoam Pyramids are a perfect combination of precision appearance and great sound control! Based on their design, Auralex Studiofoam Pyramids offer increased installation versatility (their pyramids are 4" wide, so you can do cuts at 1 foot, 2 feet, etc.) and minimal seaming. They also supply a bit of extra diffusion due to their 4-sided geometry and will give your space tasteful, upscale looks and sound.

As with 4" Studiofoam Wedges, 4" Studiofoam Pyramids are recommended for larger spaces, rooms with pronounced low-frequency problems or where sonic accuracy is mandatory and stronger absorption is required.

Having 4 sides exposed on each pyramid also yields more sound wave diffusion, which is desirable in some spaces. Generally, Auralex 4" Studiofoam Pyramids will yield less overall dryness than 4" Studiofoam Wedges.
