It is a speaker system aiming at a miniaturization, inheriting the technology of the high-end model of a Diatone.

A light weight and quantity rigidity, the organic fiber aramid equipped with the moderate loss factor, and the new aramid hybrid FRP that mixed and finished weaving the inorganic fiber amorphous silica which strength improvement was made 15% from before are adopted as the diaphragm. Thereby, little high speed play distorted also to the signal at the time of the Dainyuu power is enabled.
Furthermore, the H.D. (high dumping) suspension was adopted as edge, and the reliability over the outstanding braking force and long period of time is acquired.
Original Woofer direct connection technology is supplied to this unit, and the natural roll-off characteristic has been acquired by distributing a high region vibration of a Woofer physically. This is enabled to drive directly, without passing a network, and the high drive of purity is enabled more.

The H.D. alloy D.U.D. tweeter of 2.5cm is adopted as a high region.
In order to adopt as a diaphragm the H.D. (high dumping) alloy which is a new alloy material which controls a peculiar vibration and to employ the characteristic of this diaphragm efficiently, the D.U. D-structure which twists a voice coil around a diaphragm directly is used.
Moreover, high-resolution music expression is aimed at according to the hybrid D.M. (direct mounting) structure which mounted the plate of the magnetic circuit to the baffle directly.
In order to prevent sound reflection and radiation of a frame, processing which stuck the felt is adopted as the perimeter of a diaphragm.

The magnetic-shield design is carried out and the bad influence to TV footage etc. is prevented.

The sticking-by-pressure wiring system not using solder is adopted as a network.
Moreover, the input terminal also corresponding to a banana plug is adopted as a terminal.

The particle board with little proper tone is selected carefully and adopted as the enclosure.
Moreover, in order to reduce diffraction phenomena, it is considered as 4 side round baffle which attached R on all sides [ baffle ].

There was a speaker stand for exclusive use as an option.
While making a column part into solid structure and improving the whole rigidity, the fixed screw for the prevention from
