Description
 
The compact 3 way speaker system which supplied the loudspeaker technology original with a Lo-D, and was developed.

The 20cm cone type Woofer which adopted the gathered edge is carried in low-pass.
It asks for the sound which pressed down distortion and cleared up, and Lo-D Actuator (low-distortion magnetic circuit) is carried.
Moreover, the aromatic polyamide system fiber of new materials is adopted as a voice coil bobbin, and the heat-curing type self-fusion line is used for a voice coil. Since an electromagnetic damping is not built with a fibroid bobbin while improving an input-proof sharply by this, the low-pass play with the sufficient linearity from the Dainyuu power to a few input has been realized.

The 2.5cm dome shape tweeter which adopted the titanium diaphragm is carried in the high region.
While attaining a stabilization of a low distortion and quality, 2 piece schemes which adopted the special cloth are adopted as an edge, and the piston vibration area is expanded to it with the soft edge.

The dome shape super tweeter which small-caliber-ized to 1.4cm in the super-high region, and acquired wide dispersibility is carried.
Rigid high titanium was adopted as the diaphragm like the tweeter, and efficiency is improved with high region Tran Gent.

The enclosure serves as rosewood tone finish.
Moreover, a super tweeter and a tweeter are constructed on a unification frame, the perpendicular routing of the placement with a Woofer is carried out on the cabinet medial axis, and a lateralization and a feeling of sound field are improved.
