Product Details

Fountek FW168 6-1/2" Aluminum Midwoofer Speaker

Fountek midbass drivers offer exceptional value with premium features like aluminum cones and phase plugs, robust cast frames, and optimized low-distortion motors.  They are the perfect choice for use in high-end loudspeaker systems, paired with premium-quality tweeters like Fountek’s own ribbon units.

The FW168 6-1/2” model is similar to the smaller 5-1/4” FW146 model in design and cosmetics, but provides deeper bass extension for use in larger monitor and floor-standing speakers. It features the same cast frame and satin-anodized aluminum cone as the other Fountek midwoofer drivers, for an aesthetically seamless match.

Fountek FW168 6-1/2" Aluminum Midwoofer Speaker

What size port would produce the best response if I use the Dayton Audio TW-0.25CH 0.25 cu. ft. 2-Way Speaker Cabinet Pair Cherry? 

Asked by: DoItYourself2
In order to get a decent tuning frequency in that enclosure, the port will have to be 2" in diameter and almost 17" long. This woofer will work best in the 0.5 cubic foot cabinets, using a port that is only 2" in diameter and 8" long for the same tuning frequency.
