It is the speaker system announced as a Diatone foundation 49 year standard model.

The large caliber Woofer diaphragm of 30cm of a weight saving version is developed newly. This holds rigidity by reexamination of diaphragm form and a manufacturing process,The aramid hybrid FRP which moreover made a pulp corn, the new aramid hybrid corn Woofer which attained the weight saving to this weight, and inorganic fiber amorphous silica the Intra ply structure is adopted.
Moreover, feeling of unification, such as textures and a feeling of density, is planned by the thing which will also make allotropy material an inside region and to do.

H.D. (high dumping) alloy D.U.D. is adopted as a high region, and this is firmly supported by high rigidity frame structure D.M.
