The Ebony acoustic absorption panel is a mid frequency absorber. Its convex shape helps to reduce the first convergent angles in rooms. The front part of this model consists of a polyurethane resonant membrane in an air-box. Three other raw materials with different properties are also used inside it. In spite of its small depth the Ebony also has a reasonable absorption coefficient at low frequencies.
This product can be mounted on walls and ceilings due to its low weight.
