Answer (1 of 3): A typical speaker cone is driven by a coil glued to the center of the cone, and supported by a flexible surround on the outside of the cone as well as by a springy "spider" around the coil. Selecting the right soft parts is tough, with the most critical aspects being the materials, process, and fabrication. Polypropylene materials (also known as PP, CD, etc.) . At what I assume is about 5k, the aluminum cone driver just goes haywire. Paper cones, made in part from felt and wool have a combination of stiffness, low mass and loss inherent in the material that often make the best sounding cones. The best car spe. The paper models are less durable as they can crack from temperature changes or tear from excessive outputs, causing the cone to rip. There are hundreds of speaker cone material types.
