The point of this improvement is that the reinforcement pier is placed in the middle of the voice coil bobbin to eliminate resonance in the mid-high range and improve the input resistance.
The company is the top unitFLAT C90In the development of the voice coil bobbin, the reinforcement of the aluminum pipe is applied to the middle part of the voice coil bobbin, which reduces resonance and eliminates the vibration sound at the time of large input and the specific sound source by increasing the strength to withstand lateral stress caused by electromagnetic forces, and it is C60 applied.
CurrentC90The reinforcement of the middle part of the voice coil bobbin is not aluminum pipe, it is replaced with a reinforcement pier by a lightweight normex paper (polyamide resin), and it is higher sound quality.
C60Because of this improvement, the sound field became wider and deeper and richer.
Even when using a multi-amplifier system as a mid-range unit with wide bandwidth, it became possible to put power, and it became a unit that can be used for all purpose, so I would like to recommend it widely to customers.
