Commentary
A sealed bookshelf speaker system.
A 25 cm cone type woofer is installed in the low range.
This unit is designed for enclosed enclosures and is highly compliant and reduces distortion by making the relationship between magnetic circuit, voice coil and cone piston motion ideal.
A 3.5 cm dome type tweeter using a Mylar diaphragm is mounted in the high frequency range.
Equipped with a level control for adjusting the mid - and high-frequency range.
The exterior is finished with oil walnut, and the speaker grill is acoustically excellent.
