It is 3 way speaker system which adopted the distributed vibration type as the cabinet.

The 30cm corn type unit developed on the basis of the 2S-305 type PW-125 type which is a monitor speaker is adopted as low-pass.
The 55phix35mm Al Nico system magnet is adopted as the magnetic circuit, and the corrugation corn-shaped thing is adopted as corn paper.
Edge is a forging roll die, is not made into a perfect semicircle, but is written with right-and-left asymmetry, and nonlinear distortion is improved. Moreover, the crossing edge which performed coating with visco-elasticity also with the quality of the material is adopted.

The unit of a 12cm corn type and a 2.3cm dome shape is adopted as the inside region and the high region, respectively.

The enclosure is pressing down vibration by firm junction structure and a distributed type special reinforcement to the minimum.
Moreover, decentralization in vibration mode is attained and the cabinet makes resonance which resonates greatly there be nothing in the specific zone.

The large-sized coil developed newly is used for the coil which was being used for the network as an object for highest-class systems, and it is pressing down distortion generated from a network.
