Description
 
A tweeter common to A series is a speaker system aiming at expansion of low-pass play capability as it is.

Three 20cm corn type Woofers are carried in low-pass, and expansion of diaphragm area is aimed at.
The polypropylene corn which mixed the mica by the newly developed injection molding method is adopted as a diaphragm. This process can suppress resonance by raising the intensity of the voice coil circumference, and expansion of a dynamic range and distorted reduction have an effect

The 17.5cm corn type squawker is carried in the inside region.
The mica mixture polypropylene corn by an injection molding method is adopted as a diaphragm like a Woofer, and expansion of a dynamic range and distorted reduction are aimed at.

The 2.5cm hard dome shape tweeter is carried in the high region.
The titanium dome is adopted as a diaphragm and the division vibration constituting the cause of sharpness rung in muddiness and lug of sound is canceled, making full use of the original laser analyzing method of a CELESTION.
Moreover, the Faraday ring is adopted as a magnetic circuit and the improvement of efficiency covering distorted reduction and broadband is aimed at.
Furthermore, as for the form of the aluminum die-casting plate, the design to which the normal position of a musical instrument becomes good is carried out.

Each unit has adopted aluminum die-casting which carried out integral moulding of a frame and the face shield.

The enclosure is made into the internal structure which reinforced so that vibration and sound pressure of a Woofer could be borne.
Moreover, in order that a cabinet might obtain natural sound, real wood finishing with the Santos rosewood was given, and also the same Naked board that attached the round is adopted as the corner of four sides of a lengthwise direction.

The terminal corresponding to bi-wiring is adopted.

The spike and the insulator are attached.
