Using 28mm German soft dome sound film, special damping layer treatment, the frequency response is broad and straight, and the sound performance is more transparent and clear. High-performance ferrite dual magnetic circuit design, linear uniform magnetic field, harmonic distortion can be effectively reduced. Lower distortion and better prevention of dynamic compression, improved resonant cavity design, high-impedance sound-absorbing materials. Professional liquid magnetic cooling technology, high temperature resistant aluminum alloy frame and copper clad aluminum wire voice coil, with greater power tolerance. To protect the precious treble diaphragm, a protective net is added to the panel to prevent the diaphragm from being deformed and damaged by external forces. Adhering to HiVi' s consistent Hi-end concept, the sound is more natural and smooth, and analytical performance are more layered, and the details are rich without unpleasant characteristics.
