Description
 
The low distorted magnetism circuit which equipped the magnetic circuit of the Woofer with FN ring is adopted. Compared with the conventional thing, distortion is pressed down sharply. Moreover, corn paper is fabricated in the state near a non press so that a moderate internal loss may be given. The voice coil was also equipped with the dumpling made of the special synthetic rubber, and the clear low-pitched sound region with little muddiness has been obtained.

The dry press corn in which moderate hardness and an internal loss are acquired is adopted as the corn paper of a squawker. It is the consistency vibration design which allotted corrugation.
Still more nearly special dumping processing on the crossing edge of V type was given, and the polish is applied to clear inside and upper register.

The rigid outstanding titanium alloy is adopted as a center cap of a tweeter. Generating of division vibration was suppressed and the characteristic [ almost flat / to 30000Hz ] has been acquired.
Moreover, the special synthetic rubber is adopted as a damper.

Few coils containing a core and metallized polyester film capacitor of a transfer loss are used for a ネットー work, and low distorted-ization is attained.

The distributed vibration type enclosure which allotted a strong junction structure and a special reinforcement is adopted. Vibration mode was distributed and harmful resonance is prevented.
Moreover, a bass-reflex port is used as a twin triangle duct, and a duct with a length [ by the firm timberwork of 15mm of board thickness ] of 210mm is used for it. Furthermore, in order to prevent generating of standing-wave, a rectangular port is divided aslant and generating of the harmful vibration is pressed down by this.
