F-6a Kevlar-Paper

Key Features:
  • Light and extremely rigid cone made from Kevlar/paper composite;
  • specially made high loss rubber surround;
  • shielded double magnet motor structure;
  • high power handling aluminum former voice coil;
  • central phase plug;
  • high-density aluminum die-cast basket.
  • The design of F6 has been optimized for balanced and dynamic low bass reproduction in small or medium vented systems. Midrange clarity and tonal balance is remarkable.

F6 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. The driver utilizes a central phase plug to avoid air compression and internal air volume resonance. The plug improves frequency response and dispersion as well. The aluminum former voice coil and air transparent spider contributes to the linear operation of the transducer at high power levels.

The massive aluminum die-cast basket has been developed to minimize parasitic structural resonances.

The shielded magnet structure allows the F6 to be easily incorporated into audio/video applications. The driver may be used in a small closed box as a bass-midrange unit, when a subwoofer is employed.

Recommended crossover frequency region for two-way system design is 2-3 kHz.
