The low distorted magnetism circuit developed with metallurgical engineering approach is adopted as the magnetic circuit of a Woofer as well as a DS-90C type. A driven type nonlinear distortion is improved to below role 1 / 10 (-20dB) compared with the conventional Diatone speaker.

The polyester resin film was used for the edge portion of a squawker, special dumping processing was performed to it, and the characteristic is controlled into it.
Moreover, a low distorted magnetism circuit is adopted as well as a Woofer, and the frame is using the firm die-casting frame.

The composite material GFRP (Glass Fiber Reinforced Plastics: glass fiber strengthening plastics) is adopted as the diaphragm of the diaphragm of a tweeter. Since it is light and rigidity is high, a piston vibration region is lengthened and division vibration is suppressed.
Moreover natural frequency did not happen easily, what also has the flat high-end characteristic was obtained, and the loud sound extended smoothly is realized.

A cabinet decentralized vibration mode and has prevented resonance by this while it adopts a distributed vibration type with a firm junction structure and a distributed type special reinforcement and suppresses vibration of a cabinet.
