The Omniffusor^® U (Utility) Family are a highly durable, utility-grade polymer diffusers with lighter-weight model options in white or black. White can be used for high ceilings, such as band and choral rooms, while black can be used anywhere units are intended to be heard more than seen, such as black box theaters and behind stretch fabric installations. The U models are intended to fill both the price and performance gap between less expensive molded diffuser options and the more expensive wood options, providing a unique solution that matches the higher performance (more diffusion, less absorption) of the more aesthetically pleasing wood models at a lower price point due to the utility nature of the finish. U models use a proprietary fire-rated core with no required edge banding or finishing for cost savings. U models are available for all Omniffusor designs.
