Description
 
The book shelf type speaker system designed three ways focusing on a 25cm Woofer.
It is designed being conscious of the roughness which matches both a European-style room and a Japanese-style room.

A 25cm corn type Woofer is adopted as low-pass.
This unit is suppressing distortion by the large amplitude by adoption of the long travel voice coil original with a Coral.

A 10cm corn type unit is adopted as an inside region. It is considered as the frame direct vent system so that influence by the sound pressure of a Woofer may not be received.

The phon type unit which adopted the aluminum wire voice coil is adopted as the high region.

The enclosure serves as a bass-reflex type with which sound absorption was considered as reinforcement, in order to suppress a box resonance, and polyurethane finishing is given.
