Description
 
The 32cm unit which uses the poly craft honey cam diaphragm is adopted as a Woofer.
The honeycomb structure which joined the craft honeycomb core which carried out resin impregnation as well as the skin material which carried out impregnation of the special resin to paper-making pulp with polyamide system adhesives raised rigidity, and one about 4 times the specific modulus of paper is realized.
Examination was fully added also to impregnation resin or adhesives, paper raised the internal loss about 20%, and a frequency response and the distorted characteristic are improved.

The 10cm squawker unit which uses an original CFP corn is adopted as a mid range. A rigid high carbon fiber is added and strengthened in big polypropylene of an internal loss. Furthermore, by molding by original molding technology, the mid-high-range play with high density is realized.
ohm-titanium was used for the center cap material and the high region characteristic is improved by making an edge part into the Than Gen Shal form.

The D.U.D.ohm titanium unit is carried in the tweeter.

A network circuit adopts the circuit which attained low distorted-ization.
The Attenuator has eliminated the panel.

The distributed vibration type enclosure of high rigidity is adopted.
