Product Description:
Fountek midrange drivers offer an exceptional value while offering premium features such as aluminum cones, robust cast frames, and optimized low-distortion motors. They’re the perfect choice for use in high-end loudspeaker systems, paired with premium-quality tweeters like Fountek’s own ribbon units.
Fountek’s FW100B model is a 4″ midwoofer with an extended upper range that allows it to be used as a midbass driver, or as a woofer together with a dedicated midrange for further reduced distortion. The satin anodized-aluminum cone perfectly complements the other Fountek midwoofer drivers.
