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! 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.
