Sundown Audio 8" U-Series 1750W Peak Dual Voice Coil Subwoofers

• The U-8 can be thought of as an SA-8 v3 on performance boosters. Everything there is to love about the SA-8 v3 just with more power handling, more x-max, and more output potential.
• The Sundown U Series is THE premier “standard suspension” woofer series. The all-new U v.2 improves on the already incredible performance of its predecessor.
• The voice coil is a 2.36” long / 3” diameter 4-layer aluminum winding / aluminum former unit – which is the same coil design from the U v.1 – but the new version is built with a stronger aluminum former
