DiSorb™ Convex Diffuser-Absorbers are designed to achieve sound diffusion through their curved surfaces and absorb sound through innovative tuned componentry. Manufactured to the specification type required, these barrel diffusers provide a desirable wide-range diffusive scattering of returned acoustical sound energy and moderate absorption. DiSorb™ come in standard white or custom gel coat color with a lemon-peel texture, or they can be wrapped with a decorative fabric facing to complement your overall design and color palette. DiSorb™ Convex Diffuser-Absorbers are supplied in standard sizes and are ready for installation (with mounting hardware) to existing walls, ceilings or grid.


DiSorb™ Convex Diffuser-Absorbers are the ideal decorative wall & ceiling treatment for areas that require absorption and broadband diffusion to help scatter and blend the sounds in your space for the listening enjoyment of both music and speech. Some applications include:
