DIATONE DS-55EXV

Commentary

This AV speaker system is based on technologies developed in Pure Audio.

A 22 cm cone type woofer is installed in the low range.
This unit uses R. I. (radial injection) carbon cone. R. I. resin plus carbon fiber is injection molded using a special molding technique. In addition, the carbon fiber is radially oriented to increase rigidity. This results in a large internal loss and high specific elastic modulus, enabling high-density low-frequency playback.

A 3 cm dome type skoker is installed in the middle area.
The diaphragm uses S. R. titanium diaphragm with special surface hardening treatment of titanium. Moreover, high-speed response is realized by the D. U. D. structure in which voice coil bobbin and diaphragm are integrated and the D. M. system with high-rigidity unit structure.

A 1.6 cm dome type tweeter with S. R. titanium diaphragm is installed in the high band as well as in the middle band.

It uses a magnet shield system with anti-magnetic magnets attached to the magnetic circuit to prevent magnetic flux leakage.

The front baffle is a 4-side round baffle with round baffles on both sides and upper and lower sides to prevent sound quality deterioration due to diffraction effects.

The enclosure was available in two color variations, black and white.

There was a speaker stand for each color variation that was sold separately.
This stand can be set at an angle of elevation and can also be set normally by turning it upside down.
