Commentary

With the theme of sound image realism, this speaker system realizes clear sound image localization, excellent power linearity, and high efficiency and bright sound.

High efficiency is achieved by adopting a B-alloy (boron alloy) lightweight vibration system of 2.5 cm dome type for the high band and 12 cm balance drive type for the middle band, and by adopting a powerful magnetic circuit of large magnet.
This vibration plate is realized by forming a special thin film metal into the shape of the vibration plate and then infiltrating boron into it by a special heat treatment. This method extends the upper limit frequency and realizes sound quality with a core with excellent transient characteristics.

A 32 cm cone type woofer is used for the low range, and a light and strong straight cone is driven by a large magnet with a diameter of 156 mm.

The enclosure is designed to be symmetrical to improve the sense of orientation.
