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

A 10cm corn type unit is adopted as the inside region.
In this unit, the diaphragm rear was sealed completely and the acoustic load type which filled up that air cell with the sound-absorbing material is adopted.
The barium ferrite is adopted as the magnetic circuit.

The 3cm dome shape unit of the establishment meter is adopted as the high region.
