Sundown Audio U Series 15" 4 Ohm DVC 1500 Watt RMS Car/Truck Subwoofer U-15-D4
Sundown Audio U Series 15" 4 Ohm DVC 1500 Watt RMS Car/Truck Subwoofer U-15-D4
The Sundown U Series is the premier standard suspension series. It is the most direct replacement for the world famous Z v.3 woofer line which we produced from 2011 to 2016 before launching the new platform Z v.4 series. Due to numerous advancements in Sundown's design process the U Series is able to deliver performance on-par with the Z v.3 series but at a much lower cost.
Sundown Audio started with a double-stacked / 8.66 wide Y35 grade ferrite magnet system coupled to a one-piece, bumped T-Yoke and a 0.6 thick top-plate. Just as with the Z v.3 before it and their other high-end subwoofers they added a very thick (5 mm) aluminum shorting ring inside the magnets to reduce static inductance and level out inductance over stroke. The U series motor also features a 0.6 long pole-extension to keep the coil under control at high levels of excursion.
Highlights:
- Black Aluminum 3 voice coil former for superior heat dissipation.
- High Temperature Round-Wire CCAW voice coil with high-temp black adhesive.
- Double stitched surround.
- Heavy duty cast basket.
- Spring loaded terminals accept up to 8 gauge.
- Stitched-on double-XL tinsel leads.
- Rear vented pole piece.
- Rear drilled gap-venting.
- Innovative high-velocity cast aluminum vented frame spacer ring.
- Magnet ID shorting ring.
- Top-Plate Cooling Channels.
- Cast Aluminum surround bolt-on rings.
- Optimized for small ported or bandpass enclosures.
