DIATONE DS-77EX(Black)

Description
 
In order to harness the characteristic of a honey cam construction corn in the maximum, the carbon graphite composite which is proud of a specific modulus high as skin material is adopted.
Also paying attention to frame structure, the R.S. (high rigid support) frame made into mode-of-vibration distribution structure is adopted.

1000 filament carbon with a high specific modulus was adopted as the diaphragm of an inside region, and broadband-ization is conjointly realized with an S.R. titanium cap and the Than Gen Shal edge.
Moreover, the R.S. frame is adopted as a frame.

The S.R. titanium which performed special hard-facing processing was adopted as titanium, and the play zone is expanded to the diaphragm of a high region. Moreover, the resonance of a material is controlled with the three-layer structure by tunic formation.
The D.M. system is adopted as frame structure.

4 side round baffle which used not only both sides but the up-and-down side as the round baffle was adopted, and sound quality degradation by the diffraction effect is prevented.
