Description
 
The speaker system which followed the DS-A3 type basic design as the 3rd phase of the 50th anniversary work of a Diatone studio.

In order to make the tone of all the zones the same, the material has adopted the aramid system. The organic fiber aramid which used the aramid diaphragm for the tweeter and combines high rigidity and a light weight, and a moderate internal loss in a Woofer,The new aramid hybrid FRP which made the inorganic fiber amorphous silica which realized about 15% of high rigidity-ization conventionally the Intra ply structure is adopted.

It adheres to the power of expression of a low-pitched sound region, and a formal DS-A3 type bass-reflex system is followed. The play of the low-pitched sound which is full of weightiness which reproduces a feeling of size and weightiness of a musical instrument correctly with a small system is possible.

A network circuit selects carefully the high purity part which suppresses a transfer loss to the minimum. The gilding terminal which can also connect a banana plug is adopted as an input terminal.
