Thank you for purchasing our product. FF-WK series are full-range speaker units ideally and exclusively  
designed for a bass-reflex enclosure. The previous FF series speaker units construction has thoroughly been rede-  
signed on the FF-WK series. With a new addition of 10-cm diameter speaker unit to the product range, new tech-  
nologies such as a “double-layer” paper cone, a ridge-dome shape aluminum alloy center cap and a pocket neck  
damper have been employed for high-quality 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 non-characterized  
high frequency sound reproduction. Please read this manual carefully before use.
