Acoustic panels are designed for creating acoustic comfort in definite areas of a room. For instance, in a dining area, a bedroom, or a conference room.
They substantially reduce bad sound reflections and echoes. 
Panels are covered with natural handcrafted felt that reflects patterns of a real stone. Allow creating minimal Zen interior design.
 
Set consists of 4 panels perfectly matched by size, form, and color.
