The system consists of Ecophon Sombra A tiles and Ecophon Connect grid systems, with an approximate weight of 3 kg/m² (6 kg/m² with X-bass). The tiles are manufactured from high density glass wool. The visible surface is a matt black batch painted glass tissue and the back of the tile is covered with glass tissue. The edges are natural. For special applications i.e. cinemas, tiles with a sound reflecting surface, Sombra A/gamma, are available. To improve absorption in the low frequency range, Sombra X-bass can be installed on top of the suspended ceiling. For more information see application "Ecophon in Cinemas". The grid is manufactured from galvanized steel.
