Hi-vi Symmetric Motor Drive (SMD) technology makes the voice coil into a symmetrical driving magnetic field, thus acquiring symmetrical reducing voice coil inductance and back electromotive force modulation, improving the controllability of the speakers. The voice coil in thickened black A1 frame increases the endurance and absorbing in quantity of heat of heat of speakers and linear stroke is improved to XMAX 15.5mm and bass sensitivity by band-wound voice coil. The membrance of multiple structure in basic thickened NOPRESS paper. High rigidity structure with fine recovery an air permeability. Sp10 is a special design in bass for 2001 with excellent system.
