EchoGeo hanging rafts are a high-quality Class A acoustic absorber. Rafts are excellent at battling reverberation and echo and should be suspended directly above the noise source for optimal performance. The Echo panel core is an open cell melamine polymer which is lightweight and fibre free, finished in a wide range of industry leading Camira fabrics. Echo Raft comes with a built-in support structure for ease of installation and to improve rigidity.
