Description
 
The compact size speaker system which gave three kinds of variations united with the room.
The metal screen was made to fit red, blue, and green primary color saran, and also the design tightened by the aluminum angle is adopted.

Two 10cm corn type Woofers are carried in low-pass.
The large-sized thing of 36phix30mm is adopted as a magnetic circuit, and it has become a sky par edge type so that the large amplitude can be borne.

H-50 which is the phon type tweeter which used the duralumin diaphragm of 20micro thickness is carried in the high region.

The metal baffle is used for the front baffle in order to make a low-pass play advantageous for effective volume more greatly, and so that big sound pressure may not cause unpleasant resonance, either.
Moreover, the enclosure has structure which combined the Laminated Veneer Lumber for sound.

A network part measures an electric target with the high-speed automatic recording equipment of B&K of Denmark, and also carries what was determined by an audition test.
