Design Features:

Leading Small/Thiele parameter optimization design;

Black natural fiber ultra-light and high-strength integrated diaphragm; 

Fatigue resistance and high loss natural rubber folding ring-strong absorption of excess vibration energy;

Highly stable linear centering support piece-improving the characteristics of air compression;

All-magnet high-performance large magnetic circuit system；

HiVi’s symmetrical magnetic field (SMD) drive technology-high sound pressure distortion output；

High-density aluminum frame-eliminates harmful resonance；

 High-power, high-temperature resistance and no eddy current loss AL voice coil frame-guarantee of high-quality bass.

It is suitable for the low frequency unit in the Hi-Fi two-way phase inverted speaker system and the mid-range unit in the three-way system.
