PYRAMID® is a model that combines diffusion and absorption qualities it was devised forthe acoustic music industry to enable different acoustic characteristics with the sameaspect.This design was based on a quadratic format with flat absorption surfaces made ofacoustic foam and on curved diffusion surfaces made of EPS which give it a superiorbalance, aural and visual performance. The original PYRAMID® (PYR060), made on EPS and Acoustic Foam combineshemispherical acoustical diffusion and absorption in the same panel, and therefore themost balanced element from ATP's catalogue.There are two other options; PYR060F an absorbent made on Acoustic Foam and thePYR060E that is a diffusor made on EPS.These 3 options were designed to be applied, glued on walls and ceilings, on the modularor continuous applications, it is allowed to set on T-Ceilings as well.
