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 antiresonance and superior amplitude characteristic.
Newly developed zinc die-cast frame based on the strength analysis by the fine-element method.
Pure magnesium center cap is directly mounted onto the voice coil to make the diaphragm mechanical 2-way.
The low strain magnetic circuit using the large alnico magnet brings the low distortion and rich midrange frequency reproduction.
The normalizing processed pure iron pole piece is employed for highly transparent and natural sound reproduction in overall bandwidth.
