FaitalPRO's 10FH520 10" neodymium woofer is designed for maximum midbass punch and midrange clarity and clocks in at just over 10 pounds. An aluminum demodulation ring in the motor reduces inductance for a frequency response that extends up to 4,000 Hz, while reducing distortion. Its open cast aluminum basket makes this speaker structurally solid, while minimizing trapped air.UPC NO:'611138347419 and SKU:ADIB074L5MRLY
