The Sundown Audio U12 V2 D4 is a 12-inch car subwoofer rated at 1,750W RMS with dual 4-ohm voice coils, part of Sundown's U-Series v2 line. It is built around a double-stacked Y35 ferrite motor with a bumped T-yoke, a thick aluminum shorting ring and a pole-cap heat sink, plus a cast vent ring and 16 back-plate vents to keep the 3-inch aluminum voice coil cool. It suits people building a high-power ported or sealed system who want a rugged standard-suspension woofer that can take serious power. Against typical mass-market 12s it is heavier and more power-hungry, and it needs a strong amplifier and a properly built enclosure to give its best.

The Sundown Audio U12 V2 D4 is a 12-inch car subwoofer with dual 4-ohm voice coils. It is a standard-suspension woofer from the U-Series v2 line. It is optimized for small ported or bandpass enclosures.
The motor uses a double-stacked Y35 grade ferrite magnet system 9.44 inches wide. It has a one-piece bumped T-yoke, a 0.6-inch thick top plate and a 0.6-inch pole extension. A 5 mm aluminum shorting ring inside the magnets reduces static inductance and levels out inductance over stroke. A pole-cap aluminum shorting ring doubles as a heat sink and airflow guide.
The voice coil is 3 inches in diameter and 2.36 inches long. Cooling comes from a solid pole with machined vent channels, 16 direct air-gap vents in the back plate and cast aluminum vent rings between the frame and top plate. The frame is cast aluminum with stiffening and heat-dissipation ribs. The surround is double stitched, and the tinsel leads are stitched-on double-XL.
