The U Series woofer from Sundown is incredibly versatile, thriving in both competition setups and your daily driver. It features a double-stacked 9” wide ferrite magnet system and a robust top plate. It also incorporates shorting rings within the magnets and pole cap to enhance frequency response, act as a heat sink, and guide airflow. The U Series is equipped with a significantly thicker custom aluminum frame that boasts heat-dissipation ribs. The v.2 motor also includes an extended pole piece to ensure the coil remains controlled even under high stress!
