Commentary

This is a floor-type speaker system that uses a super labyrinth bath system in pursuit of the ideal speaker system such as creating a natural sound field without making you feel the existence of the speaker, and reproducing natural sound without peculiarity.

As a super woofer, 25 cm reinforced delta olefin cone type woofer unit is adopted.
The super labyrinth bus system of this unit realizes low-frequency reproduction at 40 hz.

The low-frequency band uses a 20 cm pure cross carbon woofer based on the MID4 concept of covering 80 Hz to 1.5 kHz, the fundamental band of human voice, with a single unit.
In addition, the ADM frame with high damping capacity is adopted.

A 5 cm dome type skoker with an ultra-lightweight aluminum (Al-Mg) diaphragm is used for the middle area.
We have succeeded in developing an aluminum diaphragm by realizing the integrated molding of an aluminum voice coil, which had been difficult in the past, with our original press machine.
In addition, the high frequency resonance is dispersed by an oval diaphragm whose central part is elliptical and becomes circular toward the outer peripheral part, and the damping material 0 is realized.

An oval-shaped 2.5 cm dome type tweeter using an ultra-lightweight aluminum diaphragm integrated with a voice coil is adopted for the high band as well as for the middle band.
Because the wavelength of the tweeter is short, it is severely affected by the reflection of the baffle plate. In order to suppress this, the enclosure is made as slim as possible, and the tweeter is spherical as close as possible to the baffle and mounted on the upper part of the cabinet.
