Swans (HiVi-Research) F10 Hi-end Woofer

Key Features:
  • Using leading technology of Small/Thiele parameters.
  • Light and extremely rigid cone made from Kevlar Paper composite-Sound is natural and accurate.
  • Germany special manufactured anti-tired high loss natural rubber surround: fully absorb unnecessary vibration energy!
  • Britain produced high-transparent and high steady spider can improve the characteristic of compliance air compressing.
  • Outside magnet high performance magnetic 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: The low frequency shocking, high analysis, energetic.
  • Suitable for bass unit of 3-way vented floor-standing loudspeaker system in home, and also suitable for sub-bass unit of sub-bass loudspeaker system.

Accurate and uncompressed reproduction of very low bass at realistic levels represents the ideology implemented in this driver. The design of the F10 has been optimized for balanced and dynamic low bass reproduction in compact or medium vented systems and subwoofers. The F10 utilizes a newly developed matrix of Kevlar and paper fibers. As a result, the cone weighs less, is more rigid, and has an improved dampening factor over conventional Kevlar¨ materials.
The back of the cone is hand coated with a special dampening compound to further maximize performance stability and control of structural resonances. This allows distortion to be kept very low through a wide frequency and power range. The massive aluminum die-cast basket with multiple point mounting has been developed to minimize parasitic structural resonance.

The driver has a vented pole piece to avoid air compression and ensure maximum power handling. Together with the long-throw design, this feature provides clean and articulated bass performance at high volume levels. The massive aluminum die-cast basket has been developed to minimize parasitic structural resonances.
