Description

  • RMS 1750 watts
  • Dual 2 or 4 ohm voice coils
  • Optimized for small ported or bandpass 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 aluminum frame was designed specifically for the U Series. It’s substantially thicker and equipped with heat dissipation ribs at the bottom of the frame. 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 controlled with machined, high-velocity pole channels and a series of 16 direct air-gap vents in the back plate.
