Single roll rubber surround. 90mm outside diameter and 74mm inner diameter of the surround.
Made of high-grade paper. Strong enough to resist scratch and stretch, a sealed round edge would block the dirt and protect the coil.
The cone(Diaphragm) is a front part of the loudspeaker. When the coil moves forward and back, drives the cone like a drum skin vibrating to make sound and into the airs.
Feature. The Paper cone has a smoother high-frequency roll-off, but the paper cone can absorb moisture from the air, changing its mass and damping characteristics.
