A compact speaker system that can be used anywhere.

A 21.5 cm cone type woofer is installed in the low range.
A delta-olefin diaphragm is used for the diaphragm, which is driven by a 4-layer voice coil using a polyimide resin bobbin with excellent heat resistance to achieve a performance of 80W and 90 dB.

A 2.5 cm soft dome type tweeter is installed in the high range.
The diaphragm is made of chemical fiber with uniform thickness and high Young's modulus and large internal loss. It is driven by a magnetic circuit using a φ 90x φ 45x13mm magnet.
In addition, it is equipped with an equalizer designed by applying computer analysis.

A level control is provided for the high-frequency band.

The enclosure uses an air-suspension system with a sealed structure.
The unit layout of the front baffle is a symmetrical type.
