At a Glance Our Concerto Acoustic Banner is the flagship of the J&C Joel variable acoustic range. As standard, it deploy two layers of Tay Wool Serge, achieving a Class A acoustic absorption rating according to EN ISO 11654:1997. The fabric is black as standard, but custom colour options are available. The Concerto offers upto 50m2 of absorbent material, with a maximum width of 6m or a maximum drop of 20m. Standard operating speed is 100-150mm/s which enables a 6m banner to deploy in 60s. Designed and Manufactured in the UK.
Acoustic Absorption The two layers of fabric are positioned at a predefined distance from a wall to reduce reverberation time. We have test reports with the fabric-wall distance at 100 & 350mm, and fabric-fabric distance at 100mm apart. The tests were conducted using a 3rd party and the full reports are available on request.
