Description
This 8 inch Woofer, features 2 inch voice coil, pulp with carbon fiber cone, and ferrite magnet motor system. As for the selection of material, this series of driver uses a new mixed material with pulp and 60% carbon fiber, it can greatly enhance the stiffness of the cone body and control range of the internal damping.
