The floor type speaker system of high-tech series.

A 20cm corn type Woofer is carried in low-pass, and the 20cm corn type mid range is carried in the inside region.
The low-pitched sound play is improved by making only a Woofer into the slope of -6 dB/oct and making a mid range unit take charge of low-pass by a network.

The 3.2cm dome shape tweeter is carried in the high region.
Power handling capability is heightened by pouring in magnetic liquid between pole piece and a yoke. Moreover, since magnetic liquid leads a voice coil to the central axis of pole piece automatically, its accuracy of a unit improves and it is enabling little distorted play.

"17AWG sky core coil", "electrolytic condenser", and "input-proof [ unguided quantity ] ceramic resistance" are used for the network part.

The enclosure is a product made from high-density particle board, a top plate and the leg serve as black mould finishing, and the black network the side excelled [ network ] in sound permeability including the front baffle is attached.
Moreover, the traditional acoustic suspension system is adopted and the low-pitched sound play is improved in air inside the enclosure by which full sealing was carried out acting as a spring supporting a corn.
