The mid bus 4 way book shelf type corresponding to digitization. It is the sound representing a Diatone which collected the essences of sound technology.
In the DS-505 type, in order to express clearly the difference in the quality of the sound of a heavy low-pitched sound region and an inside low-pitched sound region, it has 4 way composition which carries the mid bath unit for an inside low-pitched sound play.

The aramid honey cam diaphragm is adopted as a Woofer and a mid bath unit. This has realized low distorted-ization of -60--70dB (0.1% - 0.3%) proposed -20dB by higher-harmonic-wave distortion compared with a paper corn. Moreover, the polyimide film is used for a voice coil bobbin.

A boron-ized diaphragm is adopted as a tweeter and the diaphragm of a mid high. Upper register excellent in using this with the D.U.D. structure which unified the diaphragm and the voice coil bobbin was realized. The strontium magnet was adopted as the magnetic circuit and the good sharp play of the Tran Gent characteristic was realized.
