Commentary
A bookshelf speaker system using 409B.
DIG was designed and developed by Elektri, who was an agent in Japan.
20 cm coaxial type speaker unit 409B is used for the unit.
This unit has a coaxial structure consisting of a 20 cm cone woofer and a cone tweeter. A special diffuser is installed in front of the tweeter to improve high-frequency directional characteristics. The magnetic circuit is designed so that effective magnetic flux can be effectively concentrated in the voice coil. The magnets are ceramic Typhon In DACS V for low sound and Alnico V for high sound.
The crossover network is built into the speaker unit.
The enclosure uses a bass reflex system.
The exterior is finished with walnut oil stain finish and finished with direct imported oil.
It is designed with a special woven cotton wool for high sound transmission on the front and a RUNNET end plate on the lower side.
