Commentary

A compact speaker system that improves low-frequency reproduction by adopting the Doron-Cone method.

A 10 cm cone type woofer is installed in the low range.
The diaphragm is made of a mixture of two types of softwood pulp, and is made of corn paper. It is as light as 0.6g and strong as well. The magnetic circuit is equipped with a 9,000 gauss magnet.

It is equipped with a 10 cm Doron Cone to improve low-frequency reproduction, which is a problem with small speakers.
The diaphragm of this unit is made of the same cone paper as the woofer.

A 2.54 cm soft dome type tweeter is installed in the high range.
The diaphragm is made of polyester fabric with moderate softness and hardness. Acrylic damping agent is applied to improve S/N ratio. In addition, high-frequency reproduction is improved by a magnetic circuit with a magnetic flux density of 9,000 gauss and an equalizer for equalizing vibration.

The network section employs an LC parallel network in which coils and capacitors are selected with an emphasis on sound quality.

The cabinet uses a aluminum extruding material with excellent corrosion resistance and strength, and is treated with hairline finish and alumite.
In addition, a special damping material is installed inside to suppress harmful resonance.

Wall mounting is possible because it has a socket for wall hanging hook.
