Description
Fostex FF series 3" full range. A double-layer cone paper consists of two layers. One is a basic layer and the other is a surface layer. In the FF-WK series, a long-fibered (low freeness) wooden pulp is used for the basic layer, which has high rigidity realized by the large volume structure and appropriate internal loss. For the surface layer, the bincho charcoal powder is blended with a short-fibered (high freeness) kenaf, which allows to accelerate the propagation speed on the cone paper surface. The frequency response is 115Hz to 24,000Hz. Sensitivity is 86.5dB.
