Description
 
The 2 way speaker system which adopted the sandwich cone.

A 17cm cone type Woofer is adopted as low-pass.
The sandwich cone which sandwiched the thin polystyrene cone with the aluminum foil which was able to be spread uniformly is adopted as a cone.
Moreover, the long slow magnet which bears a low-distortion suspension and a large swing is used, and the play stabilized also by the Dainyuu power is aimed at.

The cone type tweeter of 3cm is adopted as a high region.
The plastic is adopted as a cone and distortion is low suppressed by winding a coil around the neck of a cone directly.

The phase response in the midrange was thought as important especially in the network, and the filter of 18 cm/oct is adopted.
