The absorber core is melamine resin foam or PET acoustic fleece, both free of artificial and natural mineral fibres, halogens and CFCs. For the fabric covering, more than 300 colours and textures are available in polyester, pure new wool, blended fabrics or non-combustible glass fabric. All products are made to bespoke dimensions.

Description
The cube absorber hangs from a single stainless-steel cable and takes up sound across all six faces. That makes it interesting for high ceilings or for ceilings with many services such as cable trays, lighting and air-conditioning equipment, and it playfully loosens up the aesthetics of the room. The cube is microporous and is finished with an acoustically transparent colour coating in white similar to RAL 9010. Alternatively, a textile cover of polyester, pure new wool or blended fabrics in various colours is possible.
