Using leading technology of Small/Thiele parameters
Light and extremely rigid cone made from Kevlar? Paper composite
Germany special manufactured anti-tired high loss natural rubber surround: fully absorb unwanted vibration energy!
Britain produced high-transparent and high-steady spider-can improve the characteristic of compliance air compressing
Linear frequency phase correcting design: the plug improves frequency response and dispersion as well.
Full sealed double magnet high performance antimagnetic system: dynamical linear drive resource.
Hi-Vi Symmetric Motor Drive (SMD) technology makes the voice coil into a symmetrical driving magnetic field, thus acquiring symmetrical driving force, reducing the mutual modulation of voice coil inductance and back electromotive force, improving the controllability of the speakers, achieving low distortion degree
Finite Element Analysis for high density aluminum frame, prevents the parasitic structural resonances
High power handling, heat-resistant Kapton?voice coil former: the guarantee of high quality bass.
Sound Features: natural, accurate, high analysis, energetic.
Suitable for bass unit of two-way vented loudspeaker system, and also suitable for mid-range unit of 3-way loudspeaker system
