Cone Type Woofer
FW208HS
Features
The new FW208HS 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 FW208HS woofer reproduces superb low
frequency sound with remarkable transient.
