It is 3 way speaker system which improved DS- 35B and was completed.

A 30cm corn type unit is adopted as low-pass.
Processing by the vacuum forming in which the fiber of an organization does not collapse is given to corn paper, and still thicker corrugation is put in.
Thereby, corn paper had a moderate internal loss, secured sufficient intensity, and is equipped with the strength which also bears the Dainyuu power.

A 10cm corn type unit is adopted as the inside region.
The polyester resin film is used for an edge portion, and the characteristic is controlled by performing still more nearly special dumping processing.

A special magnetic alloy material the linearity of magnetizing properties excels [ material ] in the magnetic circuit of low-pass and an inside region from metallurgical engineering approach is developed, the part near the magnetic pole cavity in a circuit is equipped, and the nonlinear distortion of the drive system generated from a magnetic circuit is improved to or less about 1 / 10 compared with the conventional speaker.

The 3cm dome shape unit which adopted GFRP (glass fiber strengthening plastics) as the diaphragm of a diaphragm is adopted as a high region.

The low distorted network which adopted the lamination core as the network in order to put low distorted-ization into practice, and adopted L element which considered direct-current resistance enough is adopted.

The distributed vibration type which prevents resonance is used for the enclosure, and finishing is natural walnut Veneer-Sheet finishing of a calm atmosphere.
Moreover, the acoustic image normal position is clarified by adopting a symmetrical unit layout.
