It is made from a lightweight-yet-sturdy high-impact thermoplastic, the T'Fusor Diffusor drops easily into ceiling grids and is wall mountable with pushpins, staples, nails, Tubetak, Touch Fastener or 2-sided tape. The diffusor imparts a sense of controlled spaciousness and works best when mounted with a varying alignment of the "T" pattern. Standing waves and flutter echoes are obliterated without removing acoustic energy from the space or changing the frequency content of the sound.
