Fostex FF125WK Full Range Bass Reflex 12cm Cone Speaker

[Product Description]

Two-layer pulp paper is a proprietary technology where cone paper is formed in two stages, creating a single cone paper with a base layer and a surface layer. In the FF-WK series, long-fiber (low beating degree) wood pulp is used for the base layer to enhance high rigidity through a high-structure design and maintain moderate internal losses. The surface layer is blended with short-fiber (high beating degree) kenaf and binchotan charcoal powder to increase the propagation speed on the cone surface. Additionally, the edge shape is rolled up to achieve high stroke, and a special polyurethane foam with a high-loss, high Young's modulus polycarbonate-based material is used. *The color tone of the cone surface in the FF-WK series is due to binchotan charcoal and does not use dyes. Therefore, the color tone of each cone surface varies. The center cap is molded into a ridged dome shape from aluminum alloy. It disperses and weakens strong resonance at specific frequencies, reducing high-frequency coloration. It also extends the high-frequency reproduction range by directly connecting to the voice coil bobbin. A three-point bonding method is used, where the cone paper, damper, and voice coil are bonded at the same point. This enhances the strength of the cone neck, improving high-frequency characteristics. Additionally, a pocket-shaped structure is provided in the damper neck to enable three-point bonding while using a lead wire to the voice coil. To minimize sound quality changes, gold-plated faston 205 type terminals are used for the input terminals.
