Commentary
This 2-way speaker system was developed by investing 15 years of know-how in making small speakers.
A 18 cm cone type woofer is installed in the low range.
This unit uses highly heat-resistant covered copper wire for the voice coil and has a large diameter of 48 mm Φ to improve heat radiation effect and input resistance characteristics.
A 2.5 cm dome-shaped tweeter is installed in the high range.
Titanium diaphragm is used for the diaphragm, and as with Woofer, highly heat-resistant coated copper wire is also used for this unit.
The enclosure is hermetically sealed.
The exterior is finished with Rosewood tone.
It can be hung on the wall by using the hole on the back.
