Commentary
A 3-way bookshelf speaker system that uses an ion-plated titanium dome tweeter.
A 21 cm cone type woofer is installed in the low range.
The diaphragm is made of a composite material of polypropylene and mica with reinforced corrugation by molding, and the voice coil bobbin is made of a composite material of glass fiber (GFRP) with a high input resistance design of 130W.
A 2.5 cm ion-plated titanium dome type tweeter is installed in the high range.
For the diaphragm of this unit, we introduced ion plating (IP) technology for the first time in the world to realize a lightweight and highly rigid diaphragm. This ion plating technology ionizes titanium nitride, accelerates it in a plasma state, and deposits it on the surface of titanium. Since the kinetic energy of the molecules of titanium nitride is increased, the film is deposited, resulting in a diaphragm with high deposition strength and hardness more than six times that of titanium.
A super tweeter is installed for the super high frequency band.
The enclosure has a symmetrical design.
