Commentary
B6 size 2-way compact speaker system.
A 10 cm cone type woofer with a Lo-D actuator (low distortion magnetic circuit) is installed in the low range.
The cone uses carefully selected high-compliance materials to improve the volume of the bass sound. The voice coil and bobbin are heat-resistant.
A 2.5 cm dome type tweeter using a titanium diaphragm is mounted in the high range.
The cabinet is made of aluminum alloy to prevent box squeaking and deformation.
