HIVI E8 Mid-range Driver:
Overview:
Naturally accurate, highly analytical, full of vitality and dynamic It is suitable for the low frequency unit in the Hi-Fi two-way phase inverted speaker system and the midrange unit in the three-way system. The HiVi Driver utilizes a Kevlar and paper composite cone that has lower weight, higher rigidity, and an improved damping factor.
Features:
The unit is made of a diaphragm made of carbon fiber, bulletproof fiber and other excellent acoustic materials. The ultra-light fiber material is used to expand the performance of the diaphragm to obtain a wider and flat frequency response curve, making the diaphragm more dynamic. The appearance also ensures the rigidity and stability of the diaphragm; the high temperature resistant SV copper wire voice coil is matched with the high temperature resistant AL aluminum voice coil frame; the centering piece of the high compliance CONEX material has excellent damping characteristics and dynamic stability ;External magnetic high-performance ferrite magnetic steel, linear displacement symmetrical low-distortion driving magnetic field to obtain symmetrical driving force for the voice coil; Finite element precision design integrated high-density aluminum cone frame; Optimized Small/Thiele parameter design greatly improves the unit The low-frequency sound pressure output, while reducing the distortion under loud pressure, provides a solid guarantee for the high-fidelity bass unit to reproduce the large dynamic low frequency of music.
