Description
 
The floor type speaker system of the high-tech series which inherited the technology of vartical series.

Two 20cm corn type Woofers are carried in low-pass.
By fixing a unit to enclosure both sides, the wall dip which poses a problem with a floor type is canceled.

The 20cm corn type mid range is carried in the inside region.
The subenclosure is prepared in the core of the enclosure, it is mounted, and the mutual intervention with a Woofer unit is prevented.

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.

A 17AWG sky core coil and the electrolytic condenser 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.
