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
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
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.
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.
