The Sundown U Series is our premier “standard suspension” woofer 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 our design process the U Series is able to deliver performance
on-par with the Z v.3 series but at a much lower cost.
 We start 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 our other high-end subwoofers we also add a very thick (5mm thickness)
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.
The voice coil is a 2.36” long / 3” diameter 4-layer aluminum winding / aluminum former unit –
which is the same coil we use in our X v.2 series and, thus, the U series has the same 1500-watt RMS ratings.
The coil temperature is kept in check by a heavily smoothed / high-velocity pole-vent and a series of ten direct air-gap vents in the back plate.
The U series also features newly tooled cast aluminum vent rings in between the frame and top plate to
effectively exchange air at a high velocity over the voice coil beneath the spider landing.
The U series features an all-new cast aluminum frame series to the Sundown line which allows for taller cones
than the older frames used on the Z v.3 series.
The taller cones provide enhanced coil stability and increased mechanical excursion capability.
We also tooled matching cast-aluminum surround clamps for the U series to ensure durability in the most demanding situations.
The surrounds and cone bodies have been fully custom tooled especially for the U series and are stronger / support more excursion
than the Z v.3 series cones and surrounds.
The new cone bodies also feature an indentation for the same wide-flange, ultra-strong dust caps as our new platform subwoofers.
If you are looking for a woofer that sounds similar to the SA series but handles significantly more power… the U series is exactly what you need.
It has been designed to live up to the reputation earned by our Z v.3 series both in terms of every-day music enjoyment and SPL competition.
