For example, rag is light and about well damped, but not stiff; leaf can be prepared stiff and light, but it is not mostly well damped; plastic can be light, but broadly the stiffer it is made, the less well-damped it is. As a result, multifarious cones are made of some character of composite material. This can be a matrix of fibers including Kevlar or fiberglass, a layered or bonded sandwich construction, or simply a coating applied to stiffen or cloudy a cone.

Full range drivers often employ an additional cone called a whizzer: a small, glassy cone attached to the joint between the voice coil and the primary cone. The whizzer cone extends the gigantic frequency response of the driver and broadens its big frequency directivity, which would otherwise Wireless Speakers be greatly narrowed due to the outer diameter cone material failing to keep up with the central voice coil at exceeding frequencies.
