Description
 
The DS-A1 type with the unique form which symbolizes craft Manship,The reference monitor which bears the next generation, and the technical thought cultivated with the 2S-3003 type are supplied to full, and they are the high musicality as pure audio, and 2 way system characterized by the monitor-oriented high fidelity play which excelled in the dialog play.

The B4C corn type of a 5cm aperture is adopted as a high region diaphragm. Even if compared with 5 times of titanium, and boron-ized titanium, it had one no less than 2.2 times the surprising high specific modulus of this, and also this material with the moderate internal loss which is not acquired was fabricated with metal material as a corn type, in order to extend that beautiful frequency band in the direction of a mid-high range from a high region.

The same 2S-3003 type TWF aramid honeycomb is adopted as the low-pass diaphragm. And in order to make the drive energy still purer, low distortion magnetism circuit A.D.M.C.-m (Advanced Magnet Circuit-music) which canceled distortion of a drive system from a completely different viewpoint from the former is carried. It is the pure drive circuit which pushed the newest magnetism circuit theory original with a Diatone even for the actual analysis of the musical tone ripple and where it was recommended.
Furthermore, it is the Woofer direct connection which realized the drive from amplifier in the Woofer directly, and wonderful drive purity is attained.

In the enclosure, the beautiful shoulder round cabinet of the sound which adopted the structure of the stringed instrument was developed. Conditions, such as distribution of the mode of vibration by increase of the intensity accompanying reduction of top-plate area and division of a joint, are fulfilled, and the outstanding sound quality is reproduced.
