Made from a lightweight-yet-sturdy high-impact thermoplastic, T'Fusor Sound Diffusors beat the performance of competing sound diffusors hands down and offer massive cost-savings to boot! These Class A fire-rated diffusion panels work well in most commercial uses. T'Fusors drop easily into ceiling grids and are wall mountable with pushpins, staples, nails, Tubetak, Velcro or 2-sided tape. They're white in color but may be easily painted by brush or spray. T'Fusors impart a sense of controlled spaciousness and work best when mounted with a varying alignment of the "T" pattern. Improved broadband diffusion can be achieved by filling the cavity we designed into the back of the T'Fusor Diffusor with acoustic foam or 1" rigid fiberglass.
