  • Description

    The speaker system which attained low-cost-izing and a miniaturization maintaining the sound image of STELLA Opas or the STELLA melody as much as possible.

    The device given is completely the same as the unit of STELLA Opas or the STELLA melody, and carries the 13cm corn type Woofer which a 1-inch miniaturization was made in low-pass.
    Coating processing is carried out to the paper corn which is natural material, and the five-cornered diaphragm with little coarse resonance is used for the diaphragm. Thereby, since the damping characteristic of a high region is gentle, there are few network burdens and they make the relation with a tweeter smooth.
    Moreover, low-pitched sound reproduction capability is improved by adoption of long stroke voice coil structure.

    The same reverse dome shape tweeter of 3.5cm as STELLA Opas or the STELLA melody 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.

    There were five kinds of variations in the STELLA harmony at finishing, and there were lacquer finishing (poplar, piano black, erable red) and mat finishing (a pier, an oak).

    There was a stand only for the STELLA harmony as an option.
    This stand has structure sandwiched by the top plate and the sole plate focusing on MDF material with little unnecessary resonance. Moreover, use of a screw type spike is also possible.
    Furthermore, with the STELLA harmony and a screw, it can fix firmly and can unify.
