Commentary
This is a 10 cm cone type full-range unit that pursues sound quality with a well-balanced playback band and good positioning characteristic of full range.
The diaphragm uses a wet press cone with sufficient consideration of shape and material.
In addition, urethane foam edge with excellent linearity is used for the edge.
The balance of the vibration system is maintained by pulling out the lead wire symmetrically.
Uses highly rigid titanium for the center cap.
Aluminum die-cast frame is used for the frame.
By adopting a pure copper cap for the pole piece, current distortion generated in the magnetic circuit is reduced.
By adopting a perforated pole, the pressure in the magnetic circuit when the cone paper vibrates is reduced, and linearity in the low range is improved.
Magnet with 90 mm diameter is used for the magnetic circuit.
