Commentary

A 3-way bookshelf type speaker system that uses R. I. carbon and S. R. titanium.

A 22 cm cone type woofer is installed in the low range.
The diaphragm of this unit uses R. I. (radial injection) carbon cone, which is made by mixing carbon fiber with resin and molding it radially while achieving high rigidity. This reduces distortion and expands the reproduction frequency band, while achieving both high rigidity and internal loss, and improves the rise and fall characteristics.

Equipped with 5 cm cone type skoker in the middle area.
The center diaphragm is made of S. R. Titanium, which is surface hardened in a special atmosphere. Its specific elastic modulus is 40% higher than that of conventional products. Its physical properties are close to those of porcelain and the natural sound of metal is suppressed.

A 1.5 cm dome type tweeter is installed in the high range.
This unit can play back up to 30 kHz with plenty of time, and can play back the overtones that determine the tone of the instrument beyond the audible range of 20 kHz.

It is a full-scale anti-magnetic design using double magnet structure.

The front baffle has a symmetrical unit layout and the 4-sided round baffle with all four sides rounded reduces the diffraction of sound waves.

Setting with an elevation angle is possible by using the separately sold speaker stand DK-12.
On DK-12, normal setting is also possible by turning the stand upside down.
