Cone Type Woofer
FW108HS
Features
The FW108HS is the woofer unit having high
stiffness diaphragm evolved through the fusion of
the unique sophisticated pulp materials and Fostex
original paper making technology.
Certain transduction of amplitude into air vibration,
new FW108HS woofer reproduces superb low
frequency sound with remarkable transient.
