Sonner Audio writes: "Sonner builds our speaker cabinet using a proprietary process of molding layers of selected wood to make a monocoque curve cabinet shell. This single curve shell from top to bottom creates an extremely rigid cabinet construction, much more superior than cabinet utilizing flat panel. We implement Low Energy Storage Concept in our cabinet construction. Low Energy Storage concept (LCM) is a system that allows a loudspeaker cabinet to release mechanical energy in an instant without storing or overdamping the energy in the surrounding material."
