Features
• ø145mm large ferrite magnet and 8mm top
plate are 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.
• The state-of-the-art hybrid material is offered to the diaphragm. Its ideal internal
loss and stiffness bring the propagation
velocity similar to the near-metal diaphragm.
• UDR tangential surround & spider are
equipped to realize the less anti-resonance
and superior amplitude characteristic.
• The foamed rubber is chosen for the surround material. It has the 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.
