On stage, of course, the quality of sound is instrumental. The audience is there for the pleasure of listening to excellent sound, and the artists do not want to be distracted by echoing sound. This is where IBENA CO SOUND ABSORBER CALMUC, article 9774 appears on the scene. Tested in compliance with DIN EN 354 it has sound absorption above 60% with 500-2000 Hertz and ensures a better sound on stage and off stage – and less noise is heard outside.
Our CO SOUND ABSORBER CALMUC is not permanently flame-retardant. Therefore the IFR SERGE, article 9074 was developed, which also weighs 500 g/m², but is made of a permanent FR fibre. Its appearance and feel are similar to the frequently used Wool Serge.
The SOUND ABSORBER PRO, article 9779 is made of 80% cotton & 20% viscose and is an inexpensive addition to the CO SOUND ABSORBER CALMUC made of 100% cotton.
