Commentary
Driver unit for middle and high frequency band developed based on the know-how obtained in the development of SG-370BL.
The SG-370DX has the same configuration as the SG-370BL, and the diaphragm is changed from beryllium to titanium.
This diaphragm was developed based on the know-how obtained in the development process of the beryllium diaphragm, and a more rigid titanium dome was realized by improving the molding method.
Uses Mylar (FRP) edge for the edge part.
The magnetic circuit uses a 140 mm φ magnet that uses a large amount of permendur.
