This stage series speaker system was developed with the theme of improving directional characteristics.

The stage series is equipped with a wide radiation lens, a circular acoustic lens originally developed by Coral, in each of the mid-range and high-range units. Compared with the conventional acoustic lens effect only in the horizontal direction, the Stage Series realizes a nearly non-directional diffusion angle and greatly improves directional characteristics.

For the cone paper, hollow formed cone paper (hollow molding cone paper) made by a special manufacturing method is adopted. High efficiency is realized by making it light and hard. In addition, various mixing methods are adopted for pulp, which influences physical characteristics, and transient characteristics are improved.
In addition, the S-roll type Skyper edge is adopted for the edge, and the amplitude distortion is greatly improved by improving the linearity against the amplitude.

It has a 25 cm cone woofer in the low range and a 13 cm cone squaker in the middle range.
In addition, a 9 cm cone type tweeter is installed for the high-frequency band, and a super tweeter is installed for the ultra-high-frequency band.

The front baffle is equipped with an acoustic absorption baffle. By adopting a special structure with acoustic transparency and acoustic resistance, the effect of the acoustic lens is enhanced and phase distortion due to interference between units is improved. The flat structure on both sides of the baffle surface prevents phase interference and sound field disturbance due to reflection from the surroundings.
The enclosure is sealed with a separate enclosure for the Skoker to prevent interference with the Woofer.
The exterior has a walnut finish.
