 "Semi-closed" diffusor design?
To further enhance the diffusion-qualities (probably for sound-waves coming from a bigger angle as is the case in a ceiling application) at least in one direction I may put thin panels of acrylic glas in between the rows of wells as shown in the 3D-modell. This is different from other designs that use either no panels at all or panels in both directions. Comments?
