Fullrange-Lautsprecher 6,5", 8 Ohm
Die neue FF-WK-Serie löst die FF-Serie mit Kenaf-Membran ab. Komplett überarbeitet bietet die Serie eine Reihe neuer Technologien wie eine doppelschichtige Papiermembran (Kenaf/Holzfaser), eine versteifte Staubschutz-Kalotte aus Aluminium und eine neu entwickelte Aufhängung.
