Loudspeaker cones are most commonly formed from paper pulp, but plastics (e.g., polypropylene) are also popular, and sheet material can be vacuum thermoformed (like melting hot cheese over a form), compression molded, positive/negative molded (or injection-molded) into the desired shape. Metal cones are also used. Other high-tech solutions that have achieved success include a sandwich construction with skins and honeycomb or foam cores.
The Sandwich cone structure is more homogeneous and its behavior in flex is much more superior. Because of the sandwich structure, the membrane is extremely stiff. These unique characteristics of lightness and rigidity provide control of the signal transmission speed inside the material.
The composite sandwich cone permits total optimization of the frequency response curve, thanks to the total control of three key parameters: lightness, rigidity and damping. It usually has two sheets of woven glass tissue that are “sandwiched” onto the structural foam core. The glass tissue benefits from the incredibly fine weaving of very long fibers. This choice offers a mass and a size clearly inferior to those in Aramid fibers or other Kevlar® fabrics, which generate coloration in the midrange. The cone structure is more homogeneous and its behavior in flex is much more superior. These unique characteristics of lightness and rigidity provide control of the signal transmission speed inside the material.
Cone body: Material treatment → Material cutting → Three layers assembly → Cone body forming → Cone body cutting
