Description
 
The driver unit for mid-high ranges developed based on the know-how acquired by the development of SG-370bus logic circuit.

SG-370DX has the same composition as SG-370bus logic circuit, and the diaphragm is changed into the product made from titanium from the beryllium.
This diaphragm was developed based on the know-how acquired in the development it1 of the beryllium diaphragm, and the more nearly hard titanium dome is realized by improving the molding way.

The Mylar (FRP) edge is adopted as an edge part.

The magnet of 140mmphi which uses a permendur in large quantities is adopted as a magnetic circuit.
