F6 Bass-Midrange

Hi-Vi enjoys high prestige low-midrange loudspeaker unit of the world!
The Swans M1.2 sound box that adopts the F6 is being subjected to numerous good opinions at home and abroad.
-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
