Commentary

This is a 3D (three dimensional) speaker system based on the new idea of making the satellite unit as small as possible and bringing it closer to the point sound source while allowing only one woofer unit to receive the low sound range.

An 8 cm cone type speaker is used for the satellite unit.
A compact and lightweight short voice coil is used to reduce the size and weight of the voice coil. This reduces the interference caused by the magnetic loop of the voice coil itself and reduces the second harmonic distortion.
In addition, a copper cap is used to reduce the third harmonic wave.
The vibration plate of the unit is made by mixing ascidian cellulose (fiber), which is the most crystallized in nature, with cone paper to obtain light weight, rigidity, airtightness, and internal loss. The surface of the cone paper is coated with a special coating to prevent the sound quality from changing due to humidity.
In addition, artificial leather edge is used for the edge.
A high-loss, high-rigidity engineering plastics frame is used for the frame.

By controlling the frequency characteristics of the satellite unit, high performance is achieved even when the satellite is used alone.
When using 3D, a network is installed in the woofer.

A 16 cm cone type woofer is used for the low range.
Highly crystallized plant cellulose (MFC) is refined and mixed with wood pulp produced in high latitude near the Arctic.
As a result of forming a paper layer network by integrating these two types of cellulose, we have achieved light weight, rigidity, airtightness, and internal loss.
In addition, a lead acoustic stabilizer is installed behind the magnetic circuit of the woofer unit to eliminate the effect of the reaction that occurs when the diaphragm moves.

It is equipped with a 20W mixing amplifier with a volume that can adjust the volume level of the low range depending on the location of the woofer and the type of music.
In addition, a 2-channel 15W + 15W amplifier is installed for satellite.

The enclosure has a walnut natural veneer oil finish for the woofer and walnut natural solid wood for the satellite.
