The CONVEXABSORBER® is an absorbent panel which is efficient at absorbing low and medium frequencies. It was designed to be installed on ceilings and walls.It is manufactured by combining two techniques: a box tuned to 200 Hz, which is efficient at low frequencies, and a mathematically studied absorbent labyrinth, which provides this product with an excellent performance in absorbing sound.Given its characteristics, this panel balances reverberation times and echoes in large-sized rooms, auditoriums, etc..Because of its large and convex shape, it also is a diffuser with a large dispersion surface.When the areas so require, these panels can be installed alternately at 90 angles, the dispersion thus being on two plans.The CONVEXABSORBER® panel was designed and tested in order to guarantee its high performance in controlling sound energy, by reducing resonances and reflections. It has a wide range of applications.
