New design of a magnetic circuit
We decided to re-examine the magnetic circuits of PP-1000. Having permendur to remain as the magnetic material, the shape of the yoke is newly designed.
Due to this, an excellent shape to have furthermore high efficiency and uniformity of the magnetic field is achieved.
Increased output has been achieved without increasing the weight of the vibration system.
New design of vibration system
The vibration system has been newly designed in order to pursue the best balance of the sound quality. Reproducibility of a very small sound is furthermore improved because the damping material has been changed to the selected damping material and the damping characteristics have been newly designed; thereby, it can reproduce even the atmospheric feeling.
Inheriting the high quality materials for audio sound
High quality materials for audio sounds verified for PP-1000 and other models, which are well-acknowledged until now, listed in the followings are inherited: magneto coil, pure iron coil bobbin, and wire damper made of 6N oxygen-free copper wire, cantilever made of pure boron material, etc. The DLC (Diamond Like Carbon)*1) which is well-acknowledged continues to be adopted for the body. The sound quality without fuzzy sounds has been achieved because the rigidity and vibration-damping characteristic are excellent.
*1DLC(Diamond Like Carbon) DLC（Diamond Like Carbon）is a generic name of carbon film to be produced with vapor phase synthesis utilizing ion processing; and the high rigidity and high electric insulation similar to a diamond are provided for it.
