The speaker system developed under the design concept of "demonstrating the engine performance of a proprietary unit to the maximum extent."

Two 16cm corn type Woofers are carried in low-pass.
In this unit, in consideration of relation of sound with a tweeter, coating processing was carried out to the paper corn of natural material, and also the diaphragm in which the damping characteristic of a high region has the five-cornered diaphragm form which is gentle and has little coarse resonance is adopted.
Moreover, double voice coil structure is adopted and it is made to operate as a completeness parallel drive also electrically and mechanically.

The reverse dome shape tweeter of 3.5cm is carried in the high region.
What blended bio-cellulose (natural fiber) 50% and carbon fiber 50% is adopted as the diaphragm of this unit. This was newly developed in four years, and when [ of bio-cellulose ] a detailed fiber overly wraps in a carbon fiber firmly, it is stopping an umbrella umbrella sound peculiar to a carbon fiber depended for rubbing.
Moreover, the neodymium magnet is adopted as a magnet.

Since both a high region and low-pass units have adopted the double magnet system, it does not have the influence on the cathode-ray tube by leakage flux etc.

The extremely low tweeter of fo is used with a margin, and the distorted feeling which is easy to generate near crossover frequency is stopped.
Moreover, the intermodulation distortion to an inside region is removed by driving the diaphragm amplitude of a double Woofer by a new bus reflex theory controlled to the minimum.
