Aresline’s acoustic project continues with a new entry in the Fonology collection, a line that blends acoustic comfort and stylish design. Stylized “blades of grass” give PRA' its high sound absorption capacity and excellent acoustic performance in open-space environments. Carefully designed shapes and angles improve acoustic comfort in your surroundings, and multiple modules give you the freedom to arrange your space however you like.
