Description
 
The book shelf type speaker system which took in the technological result of X-VII or X-V, and aimed at correspondence to a direct cutting disc, a PCM disc, etc.

The 21cm corn type Woofer is carried in low-pass.
What blended several sorts of wood pulp by the process original with a Coral is adopted as a corn, and edge has adopted the ferrite magnet as the roll edge and magnet in which the linearity in which compliance was highly excellent also at the time of the large amplitude of corn paper is shown.

The 6cm hard dome shape squawker is carried in the inside region.
The Coral has adopted the Mg-Cu attachment super-hard light-alloy diaphragm developed uniquely, and has realized the broadband play.
Moreover, on edge, high-quality sound-ization is attained by the Than Gen Shal edge excellent in the linearity, the large-sized back cavity which made low fo possible with allowance, etc.

The 1.6cm hard dome shape tweeter is carried in the high region.
The Mg-Cu attachment super-hard metal diaphragm is adopted as a diaphragm like a squawker.

The network has selected crossover frequency from serious consideration of a hearing, and both sides of the characteristic.
Moreover, the direct-current resistance ingredient is reduced by using for an element a coil with DT core which made the special magnetic material lamination. Furthermore, molding is given as a cure against vibrationproofing.

The particle board of sufficient thickness is adopted as the enclosure, and it is finished in the mahogany tone.
