Description
This 5.25 inch Woofer, features 1.5 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.
