Commentary

A speaker system that employs a newly developed long-stroke unit.

The low-frequency range is equipped with an 8 cm cone woofer capable of approximately twice the amplitude compared to conventional models.
This unit is equipped with a double motion damper. This damper has a wide range of normal movement at high power input and controls the stroke at excessive power input to achieve high linearity regardless of input power.
In addition, the edge portion has a cross-sectional shape that becomes thinner as it approaches the cone paper joint. In addition, weight reduction is achieved by integrally molding with the cone paper, so that long stroke can be controlled with allowance even at large amplitude.
The magnetic circuit has a plate width of 8 mm. The center pole protrudes from the plate and has a vertically symmetrical shape to expand the distribution width of the maximum magnetic flux. The long voice coil with a winding width of 12 mm provides sufficient driving force despite its small size.

A 2.5 cm dome type tweeter is installed in the high range.
A neodymium magnet with strong magnetic flux is used in the magnetic circuit of this unit, and the current distortion is greatly reduced in the used band. In addition, ultra-high polymer acrylic coated soft dome and seamless voice coil bobbin are used in order to reduce the weight of the diaphragm.

A newly developed electrolytic capacitor is used in the network section.
This capacitor uses non-etched aluminum foil and OFC lead wires to reduce current loss and enable more faithful reproduction.

The enclosure has a unique shape that reduces sound diffraction.
The exterior is made of Saperi Muck material with a uniform wood grain, and is finished with an elaborate lustrous coating.

It uses a convex pin type net catch that reduces incidental sound caused by cavity resonance and reflection.

Uses gold-plated input terminal.
