Sound diffuser panel
OptiDi Panel is a compact acoustic system with a wide range of applications. Its unique shape and colour enlivens any room and gives it a unique character, combining the visual and sound side. It is precisely molded from aluminum in two forms and two thicknesses, providing sound dispersion over a wide frequency range and optional bass absorption.
