The FW168HR is 145mm large ferrite magnet and 8mm top plate is employed. Besides, the copper cap is adapted onto the pole piece to reduce the magnetostriction. HR shape cone diaphragm is employed to realize the weight saving and stiffness property.
145mm large ferrite magnet and 8mm top plate are employed. Besides
Copper cap is adapted onto the pole piece to reduce the magnetostriction
HR shape cone diaphragm is employed to realize the weight saving and stiffness property.
State-of-the-art hybrid material is offered to the diaphragm
Ideal internal loss and stiffness bring the propagation velocity similar to the near-metal diaphragm
UDR tangential surround and spider are equipped to realize the less anti-resonance and superior amplitude characteristic
Foamed rubber is chosen for the surround material
Has lower density, lighter weight and higher internal loss characteristic than the conventional rubber and the foamed rubber surround has the low young’s modulus and less eigentone
