Sundown Audio Sundown Audio SA-Series v.2 15" Subwoofer
1250 Watts RMS / 2500 Watts Peak Dual 2 or 4 ohm voice coils Vented magnetic gap & pole piece Aluminum 2.75” voice coil former for superior heat dissipation Innovative high velocity, cast aluminum vented frame spacer ring Magnet ID faraday ring for smooth acoustic response High-temperature copper voice coil wire Spring-loaded terminals Stitched-on double “XL” tinsel leads This SA-10/12/15 v.2 series is a top-down upgrade from the original SA series. The 2.75” coil punches way above its weight, outperforming many 3” coils without the adding weight & with the added advantage of a wider spider. We are able to perfectly balance the mass, motor force, and suspension stiffness for the intended power level.The motor also features a large magnet shorting ring (faraday ring) to reduce distortion and deliver smoother response across the entire acoustic spectrum. The motor & coil setup is mated to an extremely robust multi-layer spider with fully tied-on & doubled-up “XL” tinsel leads. A competition-grade paper cone, strong foam surround, and cast aluminum frame are used to complete this masterpiece. On top of the ~19mm of one-way linear excursion we have an x-mech limit of 37mm one-way before coil bottom making it nearly "bottomless."The 18" model features a larger diameter motor to drive the higher mass.

Sundown Audio Refurbished Sundown Audio U-Series v.1 12" Subwoofer
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.

The U-8 features a full 18mm of one-way linear excursion and mechanical capacity in excess of double the linear limits (around 2.5” peak-to-peak) to ensure that mechanical failures are nearly impossible. As with the SA-8 v.3 it features a surround that mimics the geometry of our large Mega-Roll v.2 surrounds for incredible linearity.
