Commentary

A small speaker system using a full-range unit.

The unit is equipped with a 9 cm cone type full range speaker.
In this unit, the fo is lowered by improving the cone paper and the edge, and the low-frequency reproduction capability is improved, and the roll edge of soft urethane foam is adopted for the edge part.
The center cap at the center of the cone is a dome-shaped dust cap made of a Mylar with evaporated aluminum. The dust cap functions as a dome-shaped tweeter, effectively reducing the weight of the cone and improving the high-frequency characteristics.
Uses a 70 φ magnet for the magnetic circuit to achieve high efficiency.

The enclosure is hermetically sealed.
By examining the beating degree of corn paper and the sealing degree of the enclosure, a sound with a sense of tightness is obtained.

There were 2 kinds of variations of the exterior, Oceania cheeks oil finish and white finish.
