DIATONE DS-203

Description
 
It is made to drive smoothly without stress by adopting a 16cm aperture suitable for a play of a vocal zone as a Woofer, it being lightweight, adopting a rigid high aramid crossing diaphragm, and adopting a mass cabinet.
Moreover, while achieving the further weight saving by abolishing resin (pitch), a feeling of S/N was raised, and by loading of an H.D. (high dumping) suspension or an A.D.M.C.-m magnetism circuit, while being thick by low distortion, the compass play is realized.

The B4C (pure boron) diaphragm with a high internal loss with a high sonic value is adopted as a tweeter with the good 4cm corn type of a 16cm Woofer and matching.
Population leather was stuck on the perimeter of the unit and unnecessary vibration and primary reflection of a sound wave are controlled.
The low distorted play without muddiness is enabled by such consideration.

2 way speaker system of the Tallboy type which inherited the DS-205 type design philosophy and put on rich sound and pliant and delicate music power of expression of sounding the Woofer of a small caliber with the large enclosure comfortably.

Capacity of the cabinet was set to 60L and rich sound is realized by large-bore-izing a bass-reflex port. Moreover, the comfortable and calm tone is realized by abolishing use of a reinforcement as much as possible.
A large-sized round cabinet like DS-205 type is completed by a Tallboy type.
The pleuron of this large-bore round distributes an oscillating fulcrum in the whole cabinet to the vibration from a unit while it is turned and crowded with lamination R plywood from both sides to the front and the back and maintains high intensity. And by pressing down the diffraction of the emitted sound wave to the minimum, it contributes to the pure play without muddiness. Pleuron is what carried out heating integral moulding of the native wood material to it having spent many hours on crossing lamination large-sized R form, intensity is high and its form stability is improving.
In order to be echoed beautifully, the Canadian maple is used for an internal joint.
