Commentary

As an improved version of the DS 500, this is a History Series speaker system that uses a 2-way configuration that emphasizes balance and is designed to fit into your room and life.

With the goal of naturally reproducing all bands, it is a 2-way configuration and the same diaphragm is used for two units. By this, it is completed as an isosonic system that realizes smooth connection and excellent sound localization.

It uses an 18 cm cone type woofer for the low range and a 2.5 cm dome type tweeter for the high range.
S-L. C. P. (Super Liquid Crystal Polymer) is used for the diaphragm. This diaphragm is a liquid crystal polymer with high fluidity and high heat resistance. It is designed to expand the reproduction frequency band and reduce the distortion factor by the development of high-speed injection molding technology and multi-layer structure by addition of carbon fiber. Compared with conventional L. C. P., this diaphragm has a specific elastic modulus approximately twice and internal loss exceeds that of paper.
In addition, the D. U. D & D. M. method (a unit structure in which the magnetic circuit is converted into a frame as it is) is adopted for the tweeter to achieve high speed.

The network structure employs the Through the Network developed by Diatone for broadcasting station monitors. By physically dispersing the high-frequency resonance of the woofer and acquiring natural roll-off characteristics, the woofer network is no longer required and high-purity transmission is possible.
In addition, the transmission method to the tweeter employs a crimping wiring method to increase transmission purity.

The enclosure uses the beautiful sound disappearing spruce straight grain veneer used in guitars etc. for the baffle plate, and walnut veneer for the body plate.
In addition, the 4-side round baffle prevents sound diffraction.

The all-wooden stand was sold separately.
