Feature

●2-ply laminate paper is a unique technology that consists of one piece of cone paper with two layers of cone paper between the base and the front layer. The FF-wk series uses long fiber (low tapping resolution) wood pulp for the base layer, which has high rigidity and moderate internal loss, and the surface layer contains Kennaf and Binchotan Charcoal powder to increase the rate of propagation of corn paper surface. In addition, the edge shape is uprolled to create a high stroke, and the material is made of urethane foam that has a special blend of polycarbonate-based materials that have high loss, high yang rates. The color of the FF-WK Series Corn paper surface is made from Binchotan and does not contain dyes. Therefore, the colors on the surface of the corn paper may vary from one another
●Aluminum alloy center cap molded into a ridge dome shape. Reduces high range coloration by dispersing and weakening strong resonance at certain frequencies. It also extends the high frequency playback band by connecting directly to the voice coil bobbin
●Uses a 3-point adhesive method that bonds corn, dampers, and voice coils in one place. The strength of the corn neck increases the high range characteristics. In addition, the pocket shape on the damper neck part allows for 3 points of adhesion while using a relay line on the voice coil
●In order to minimize sound quality change, the input terminals are made with gold-plated fast 205 type terminals


Description

Product description

The FF-wk series is a full-range unit designed specifically for bass reflectors with a new 4.0 inch (10 cm) aperture in the lineup. With the use of a 2-layer laminated paper cone, the ridge dome shaped aluminum alloy center cap and pocket neck damper, this product achieves a high frequency playback that is both vivid and realistic with a powerful low range and a character-less feel.
