Commentary
A speaker system in which W & D technologies such as fine ceramics into easy-to-use sizes.
A 25.5 cm fine ceramic cone woofer is mounted in the low range.
This diaphragm is made by adding a special adhesive to fine ceramic fiber, polishing it like a paper cone, and then press molding it at a high sound. Unlike metal, this diaphragm can give appropriate internal loss and does not easily cause peaks or dips in frequency characteristics.
In addition, it uses a sealed edge to suppress the distortion component and a sandwich lock structure that rigidly connects the frame to the baffle.
A 7 cm compound skoker is mounted in the middle area.
A fine ceramic diaphragm has been adopted for the diaphragm, and the dome shape has been improved and vibration transmission loss has been reduced.
The high-frequency band is equipped with a dynaflat ribbon tweeter mkVb with further improved input resistance and thermal distortion characteristics.
The enclosure uses softwood particleboards and is made solidly by the high-pressure flash consolidation method.
The sound absorbing material inside is made of 100% wool.
The network wiring is also caulked to prevent the deterioration of sound quality caused by soldering.
