It is the speaker system which added improvement based on DS-251 and was made.
A 25cm [ which adopted the aluminum die-casting
frame with a wall thickness of 4mm as low-pass, and raised intensity ] corn type
unit is adopted.
Corn paper is using the tough thing so that the internal
sound pressure of an acoustic air suspension may be borne.
A 5cm corn
type unit is adopted as a high region.
A 3cm corn type unit is adopted
as the super-high region.
This unit has adopted 70micro in thickness of hard
aluminum at effective oscillating 1.2cm in radius, and is finished with a

Moreover, directivity is also improving by
considering it as the edgeless cabinet which took the edge of the baffle-plate
Moreover, the stainless steel pipe is used for a saran
The thing of a stepper type is adopted as a level control, and
