YAMAHA NS-1classics

Commentary

The speaker system of Classic sushi's was developed with the theme of reproducing ability in which you can enjoy music in wide range.

A 16 cm cone type woofer is installed in the low range.
In this unit, the diaphragm has a catenary shape to enable glossy medium range reproduction. In addition, it uses a mixture of polypropylene and mica, which maintains supple strength, to achieve sound quality that does not break down to high frequencies. The mica content is determined by the best balance between strength and internal loss through repeated cut-and-try cycles, and clear sound is acquired from low to medium range.

A 3 cm soft dome type tweeter is installed in the high range.
The diaphragm is made of cotton, impregnated with phenolic resin, and thermo-molded. The cotton has been selected through repeated trial listening and consideration has been given to reducing the volume of phenolic resin to the minimum.

An Alnico internal magnet is used for the magnetic circuit of each unit.
The magnet is placed under the center pole of the unit, and the inner magnetic type surrounded by the pot type yoke reduces the leakage flux and is suitable for AV use.

The rear baffle is equipped with a tweeter level attenuator.
You can adjust the acoustic balance with the low range according to the room capacity of the listening room.

The enclosure is hermetically sealed.
The exterior is finished with real wood of birch. The entire surface including the rear baffle is made into a veneer, and the mirror surface is finished by urethane glazing coating from above.

There was a speaker stand sold separately.
African paddock is used for the base and support part of the stand, and steel is used for the plate part.
Plate part has black baking coating, base part and support part have oil finish.
