D620II adopts independent crossover design, so that the high and middle and low frequency signals are fully restored, the frequency response is broad and straight, the connection of each frequency band is also smoother and natural, the audio and image focus is accurate, the sound is round, and the sound field broad.

Its appearance design is simple and elegant, with the black vibrating cone of the woofer, majestic, noble and elegant. And its blackened cast iron frame shows its excellent quality. Both the midrange and tweeter units have a black main body style, and the appearance structure is also easy to install and adjust.

The woofer uses the German advanced Kevlar/natural fiber ultra-light and high-strength integrated diaphragm. The Kevlar bulletproof fabric fiber has super kinetic energy absorption capacity, and the natural paper-based fiber has a more natural and neutral sound. These two high-quality materials are made The diaphragm combines their excellent characteristics, laying a good foundation for the speaker to reproduce clean and natural sound. Coupled with a special fatigue-resistant natural rubber folding ring, a high-power 76mm high-temperature-resistant copper-clad aluminum wire voice coil with a Kapton voice coil frame without eddy current loss, and a high-performance ferrite magnetic circuit, it provides sufficient and long-lasting low-frequency power for the system. So that the woofer can still play calmly in the long-term high-power working state.

The tweeters all use high-performance rubidium iron boron sandwich magnetic circuit, high magnetic flux density, hand-made German woven dome diaphragm and rotationally symmetrical vibration components, voice coil and high-power 50mm aluminum skeleton, double-layer rectangular cross-section wire winding , The soft lead is led out symmetrically at 180 degrees. The entire vibrating part is extremely light, stable and durable, even at high power levels.

HiVi’s consistent HI-END concept and excellent crossover core technology, this D series professional car speaker system will definitely bring you high-quality music enjoyment to your driving life.
