A 25cm corn type unit is adopted as low-pass.

A 10cm corn type unit is adopted as the inside region.

The barium ferrite is adopted as the magnetic circuit.

The 3cm dome shape unit of the establishment meter is adopted as the high region.
The diaphragm made of polyester resin is adopted, and braking is applied by micron glass wool so that slight unusual operation may not be allowed, either.
