When Wedges won't do the trick. 4" Studiofoam Pyramids are recommended for larger spaces, rooms with pronounced low frequency problems, or where sonic accuracy is mandatory and stronger acoustic absorption is required.

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