The 4" Studiofoam Pyramid-22 acoustic panel from Auralex is a recommended treatment for medium to large areas like concert halls, gymnasiums and churches, rooms with pronounced low-frequency problems, or where sonic accuracy is mandatory and maximum acoustic absorption is required.
Having 4-sides exposed on each pyramid provides more sound wave diffusion, desirable in certain spaces and yielding less overall dryness than 4" Studiofoam Wedges.
Great looks and great sound control for just about any application
Supplies extra diffusion due to 4-sided geometry
Provides up to 24 ft2 of coverage
Pyramid cut offers versatility during installation - many different shapes and sizes are possible and provides virtually seamless installation
