FF 165WK
FF-WK series are fullrange speaker units ideally and exclusively designed for a bass-reflex enclosure. The previous FF series speaker units construction has thoroughly been redesigned on the FF-WK series. With a new addition of 10-cm diameter speaker unit to the product range, new technologies such as a doublelayer paper cone, a ridgedome shape aluminum alloy center cap and a pocket neckdamper have been employed for highquality sound. Even with these new technologies, FF-WK series inherit the previous FF series bright and realistic sound character, and achieve a powerful low sound and noncharacterized high frequency sound reproduction.

Even with these new technologies, FF-WK series inherit the previous FF series bright and realistic sound character, and achieve a powerful low sound and noncharacterized high frequency sound reproduction.
Key features:
- 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 up-roll edge shape realizes a long stroke. A polycarbonate series material which has opposite physicalities of high loss and high Young’s modulus is specially blended with urethane foam.
- A ridge-dome shape center cap made of aluminum alloy is employed. Dispersing and deadening a resonance occurred at a specific frequency with this cap helps to ease an unnecessary sound coloration at high frequency range. Also direct coupling with the voice coil bobbin expands the high frequency response.
- 3-point gluing which glues the cone paper, damper and the voice coil at one point is employed on the FF-WK series. Increasing the strength of the cone neck section realizes an improved high frequency response. Employing the pocket shape at the damper neck section has realized the 3-point gluing even with the usage of junction cable.
- In order to minimize the sound variation, the Faston 205 gold coating connection terminal is employed as a speaker terminal.
