[QUOTE="Doxquzme, post: 8865404, member: 689267"] Paper/fiber, pressed/unpressed cellulose or paper/glass fiber sandwich cones are used quite a bit in top of the line subwoofers manufacturers. It's light, it's stiff and provides a great balance between stiffness and weight. At the end of the day in high end subs, they have a specific goal in mind, usually at those price points, it's all about which material meets that objective. polypropylene is less expensive ands it too is usually impregnated with fibers ot mica, something other than the plastic to stifin things up. It's a less expensive material and is easy to shape. Some general info.
