Sundown Audio U-Series v.2 10" Subwoofer

RMS 1750 watts Dual 2 or 4 ohm voice coils Optimized for small ported enclosures Aluminum 3” voice coil former for superior heat dissipation High-temperature copper voice coil Double stitched surround Heavy-duty cast basket Spring-loaded terminals accept up to 8-gauge wire Stitched-on heavy-duty tinsel leads Solid pole with vent channels and aluminum shorting ring cap Rear gap-venting Top-Plate Cooling Channels Designed to be at home in the competition lanes or playing your favorite music, the U Series is the premier “standard suspension” woofer in the Sundown lineup. A double-stacked 9.4-inch wide ferrite magnet system is coupled to a thick top plate. A thick set of shorting rings are used inside the magnets and on the pole cap, smoothing out frequency response while doubling as a heat sink and airflow guide. A custom, substantially thicker aluminum frame was designed specifically for the U Series, equipped with heat dissipation ribs. The U v.2 motor also features an extended pole piece to keep the coil under perfect control under high stress. The coil temperature is kept in check via a high-velocity solid pole / machined pole channels arrangement and a series of 16 direct air-gap vents in the back plate.
