B11

B11 develops and manufactures lightweight, free-standing and suspended room-acoustic objects in Edling, Bavaria. Founded in 2011 by Dirk Huber, the brand stands for distinctive, design-led acoustic solutions „made in Bavaria“. The core range is based on melamine resin foam (Basotect) with a textile cover (Camira Nexus/Lucia): the TOWER OF SILENCE acoustic column, the CUBE, the square WING, the rotatable ROTARY WALL and the suspended FLYING WALL room divider. B11 also offers a PET line made from recycled ARCHISONIC Felt (Impact Acoustic) and the through-dyed WING UNICOLOR. Sound absorption is documented per product — via accredited measurements (Müller-BBM, University of Stuttgart) or manufacturer data sheets; free-standing single objects as the equivalent absorption area A per object.
