Product Details

Fountek FW146 5-1/4" 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’re the perfect choice for use in high-end loudspeaker systems, paired with premium-quality tweeters like Fountek’s own ribbon units.

The FW146 5-1/4” midwoofer is the perfect choice for compact mini-monitor speaker projects, or as a midrange in a three-way configuration together with a dedicated woofer. The aluminum cone and phase plug feature a discreet, stylish satin anodized finish, and the cast frame adds structural rigidity to the driver.
