Made from a lightweight yet sturdy high-impact thermoplastic, Auralex T'Fusors beat the performance of competing sound diffusors hands down and offer massive cost savings to boot!

Auralex T'Fusors drop easily into suspended ceiling grids and are wall mountable with pushpins, staples, nails, Tubetak Pro, TapePak Mounting Tape, or Velcro®. They're white in color but may be painted easily by brush or spray.

Auralex 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 1" ledge we designed into the back of the T'Fusor with SonoFiber, SheetBlok or 1" Mineral Fiber Insulation.
