Refurbished Sundown SA-8" v.1 & v.1.5 Subwoofer

It will take on average, 2-14 days for a subwoofer to be built and shipped. The SA8 v.1 and v.1.5 use the same motor and coil, but the change to v.1.5 brought on a new cone, spider, and basket. Because the v.1.5 has far superior parts, all motors will be built up with v.1.5 parts. All you'll need to pick is the impedance of the coil. Dual 2ohm or Dual 4ohm. **Please understand that this is a refurbished subwoofer.** Explanation of a refurbished subwoofer: Sub may have scratches, blemishes and not look 100% brand new since we are re-using a working motor and frame (unless a new frame is requested upon purchase), and installing brand new parts inside i.e. cone, coil, spider, triple joint ring, and dust cap. This subwoofer will function just as new and comes with a 30-day guarantee against build defects. INFORMATION BELOW IS TAKEN FROM THE SUNDOWN WEBSITE Several versions of the SA-8 v.1 exist -- you can CLICK HERE to help determine which one you have. The SA-8 v.1 features a heavy duty 2" copper voice coil and a double layer sandwich spider pack to support it's high level of excursion and to facilitate it's tremendous output potential. It features the same unique voice coil ventilation system seen on the SA-10/12/15 woofers to help it achieve industry leading thermal power handling. As with all Sundown Audio woofers the SA-8 is made to work in SMALL enclosures. By small we mean 0.5-0.6 cubic foot ported boxes. Due to the VERY strong motor of the SA-8 we DO NOT suggest using them in large enclosures.

Refurbished Sundown SA-8" v.2 Subwoofer

It will take on average, 2-14 days for a subwoofer to be built and shipped. **Please understand that this is a refurbished subwoofer.** Explanation of a refurbished subwoofer: Sub may have scratches, blemishes and not look 100% brand new since we are re-using a working motor and frame (unless a new frame is requested upon purchase), and installing brand new parts inside i.e. cone, coil, spider, triple joint ring, and dust cap. This subwoofer will function just as new and comes with a 30-day guarantee against build defects. INFORMATION PULLED FROM SUNDOWN WEBSITE The SA-8 v.2 represents the pinnacle of low distortion, ported box 8 inch subwoofer technology. Every piece of the SA-8 v.2 has been custom tooled with the utmost performance and lowest distortion in mind. We started with a proprietary FEA optimized motor design made just for the SA-8 v.2 which features double farady rings just like it's bigger brothers. This motor is mated to a custom tooled and patented (US Patent D691595) frame which allows for a larger spider and superior clearances to nearly any other 8" woofer on the market today. The spider itself was custom tooled to achieve a very even compliance curve and also features double, tied down tinsel leads to handle incredible amounts of power. The SA-8 v.2 also features a full 16mm of Klippel verified one-way linear excursion and mechanical capacity in excess of double the linear limits to ensure that mechanical failures are nearly impossible at any reasonable power level. The SA-8 v.2 takes a departure from it's larger cone diameter siblings in terms of the voice coil ventilation. We still use our "trademark" vented spacer ring but the SA-8 v.2 features a solid pole piece to allow the maximum level of magnetic flux to pass through it. As the SA-8 v.2 uses a 2" coil there is less steel in the pole than with a larger diameter coil so we preserved all of it. We still took great care to fully test and optimize the ventilation in the SA-8 v.2 to ensure thermal reliability even under the most punishing conditions. As with our SD-2 series the solid pole also allows mounting directly against or very close to the enclosure back-wall; thus reducing the effective depth requirement of the woofer. As the SA-8 v.2 is already very deep for an 8" woofer this is a very important feature when presented with tight mounting requirements. The standard SA-8 v.2 features a 4-layer copper voice coil for the most possible low-end extension. We do offer SPL models with lighter coils and even "extreme SPL" models with harder spider packs and other impedance configurations (these must be custom built). We can use anywhere from 2 to 6 spider layers on SPL versions to tailor the FS where it needs to be for a given SPL application.

Refurbished Sundown SA-8" v.3 Subwoofer

It will take on average, 2-14 days for a subwoofer to be built and shipped. **Please understand that this is a refurbished subwoofer.** Explanation of a refurbished subwoofer: Sub may have scratches, blemishes and not look 100% brand new since we are re-using a working motor and frame (unless a new frame is requested upon purchase), and installing brand new parts inside i.e. cone, coil, spider, triple joint ring, and dust cap. This subwoofer will function just as new and comes with a 30-day guarantee against build defects. INFORMATION BELOW IS TAKEN FROM THE SUNDOWN WEBSITE SA-8 v.3: The SA-8 v.3 represents the pinnacle of low distortion, ported box 8 inch subwoofer technology. We built on our experience with the SA-8 series dating back to the original model which launched in 2010 to create something completely unique to the market. Every piece of the SA-8 v.3 has been custom tooled with the utmost performance and lowest distortion in mind. We started with a proprietary FEA optimized motor design engineered just for the SA-8 v.3 which features a large aluminum faraday right for low magnetic and inductive distortion levels. This motor is mated to a custom tooled and patented (US Patent D691595) frame which allows for a larger spider and superior clearances to nearly any other 8" woofer on the market today. The spider itself was custom tooled to achieve a very even compliance curve over its entire range of stroke and also features large tied down “XL” tinsel leads to handle incredible amounts of power and abuse. The SA-8 v.3 features a full 16mm of Klippel verified 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. We also tooled an all new surround for the v.3 update with the same incredibly linear geometry as the Mega-Roll v.2 surrounds found on our larger woofers (X v.2 series and larger). The SA-8 v.3 takes a departure from its larger cone diameter siblings in terms of the voice coil ventilation. Just like its predecessor, the SA-8 v.2, we employed a solid pole-piece to maximum magnetic flux in the motor – but in order to reduce mounting depth we did not use a vented frame spacer and, instead, drilled vent holes around the basket base. In order to exceed the thermal performance of the v.2 model we added sixteen chamfered gap vents to the back plate to keep the high-velocity air flowing over the voice coil. In other words – the SA-8 v.3 will give you everything that you loved about the v.2 but with even more durability & even lower distortion. The standard SA-8 v.3 features a 4-layer copper voice coil wound on a black anodized aluminum former for the most possible low-end extension. We do offer SPL models with lighter coils and even "extreme SPL" models with harder spider packs and other impedance configurations (these must be custom built). We can use anywhere from 2 to 6 spider layers on SPL versions to tailor the FS where it needs to be for a given SPL application.

Refurbished Sundown SA v.1 (Original Black Motor) Subwoofer

It will take on average, 2-14 days for a subwoofer to be built and shipped. **Please understand that this is a refurbished subwoofer.** Explanation of a refurbished subwoofer: Sub may have scratches, blemishes and not look 100% brand new since we are re-using a working motor and frame (unless a new frame is requested upon purchase), and installing brand new parts inside i.e. cone, coil, spider, triple joint ring, and dust cap. This subwoofer will function just as new and comes with a 30-day guarantee against build defects. INFORMATION BELOW IS TAKEN FROM THE SUNDOWN WEBSITE SA-10/12/15 Original Black Motor: The Sundown SA series has been our most popular product line since the introduction of the SA-12 in 2009. It was the result of over a year of testing and prototyping until all of our goals and expectations were blown away. The SA series has continually evolved over the years thanks to extensive testing and feedback from our SPL competition Team and our customers but still stays true to its legendary design heritage. It has never failed to prove itself year-in and year-out in every application ranging from daily musical builds to all-out SPL competition vehicles. When designing the SA series we started out with an FEA optimized motor & coil design capable of 19mm of one-way Klippel verified excursion and just over 33mm of x-mech. This motor & coil setup was then mated up to an extremely robust double-layer Nomex spider with fully tied-on “XL” tinsel leads (84-Strands of Conductor), an SPL competition grade paper cone, and a strong foam surround. The motor also features a large magnet ID shorting ring (faraday ring) to reduce distortion causes by inductance & inductance variation over stroke. We realized that this still was not enough to meet our goal of delivering the best driver on market in this price range to our customers. To that end we designed a highly optimized voice coil cooling system that has since found its way into almost every other subwoofer we make to this day. This system allows our 2.5" coil to match and exceed the thermal performance of many competing 3" coil drivers on the market without requiring the usage of a much heavier voice coil than required for the design. The result is that the SA features the ideal mix of mass & stiffness to give you the best performance in nearly every type of enclosure.All of this hard work and engineering has led to the incredible reputation now enjoyed by the SA series worldwide. We are very proud of what these woofers are capable of and we believe that they are one of the best woofers on the market today hands down for the money.

This subwoofer will function just as new and comes with a 30-day guarantee against build defects. INFORMATION BELOW IS TAKEN FROM THE SUNDOWN WEBSITE 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. Features & Technology: Xmax = 30mm one-way by 70% BL RMS Power = 1500-watts * Heavily vented magnetic gap * Optimized high-velocity pole vent * Innovative high-velocity vented frame spacer ring Black Aluminum 3” voice coil former for superior heat dissipation High Temperature 4-Layer Round Wire Coil Large aluminum Faraday Ring (Magnet ID) Spring Loaded Terminals Stitched-On Double-XL Tinsel Leads to prevent fatigue and failure Bolted-On Surrounds Bolted-On 100% Nomex Spiders High-Strength Cast Aluminum Frame Optimized for small ported & band-pass enclosures”

This subwoofer will function just as new and comes with a 30-day guarantee against build defects. INFORMATION BELOW IS TAKEN FROM THE SUNDOWN WEBSITE The Sundown X-8, along with all other 8s in our line, is a unique driver within its line-up. Contrary to the design of the other X subwoofers the X-8 is more of an SPL oriented subwoofer. The X-8 suspension design (spider & surround) were designed around creating larger peaks for SPL purposes. It is built on our patented 8” subwoofer frame (US Patent D691595) just like the SA-8 v.3 so it shares the same massive mechanical clearances (2.5” p-p allowable). For the X-8 v.2 we removed the vented spacer ring as we did on the SA-8 v.3 and added the same high-velocity vent-holes around the frame base below the spider. This allowed us to reduce the mounting depth a bit to expand installation options. We also added a series of machined channels down the full height of the pole to increase air based cooling and also to reduce audible air velocity though the motor. The spider is a unique, progressive roll unit two layers thick. This spider was heavily FEA optimized to do the trick job of allowing large excursion capacity with a 2.5” coil on an eight inch subwoofer. The surround features a geometry very similar to the “SPL” cone options on our large woofers in a bit smaller size to suit the excursion capacity of this woofer. Both parts of the suspension support levels of excursion in excess of the linear limits of the motor & coil design. While the X-8 is more of an SPL optimized woofer it does feature the highest linear x-max of any 8” in our line at a full 19mm one-way. It also features a very thick magnet ID shorting ring just like the SA-8 v.3 as well so will enjoy the same benefit of lowered inductive distortion. Make no mistake, the X-8 is still a very clean sounding subwoofer. If the sound of the SA-8 is too smooth for you – meaning you want a more aggressive & punchy sound – then the X-8 is the woofer for you. If you want the highest SPL output from any 8” woofer in our line – then the X-8 is, once again, the woofer for you.

Refurbished Sundown X v.1 Subwoofer

It will take on average, 2-14 days for a subwoofer to be built and shipped. **Please understand that this is a refurbished subwoofer.** Explanation of a refurbished subwoofer: Sub may have scratches, blemishes and not look 100% brand new since we are re-using a working motor and frame (unless a new frame is requested upon purchase), and installing brand new parts inside i.e. cone, coil, spider, triple joint ring, and dust cap. This subwoofer will function just as new and comes with a 30-day guarantee against build defects. INFORMATION BELOW IS TAKEN FROM THE SUNDOWN WEBSITE The X series is the first driver in the Sundown woofer line-up to offer our "ultra high excursion" suspension and frame designs. The 10, 12, and 15" models feature our custom tooled and patented frames (US Patent Numbers D691596, D691597, D691598) and the 18" model uses the tried and true 18" 6-spoke with a custom tooled adapter to allow for a full 10" diameter spider. We mate these new platforms to a triple stacked 190mm diameter motor structure featuring a hyper-extended pole and extreme clearances (allowing up to 4" p-p travel before mechanical bottom). This motor powers a 3" diameter 4-layer CCAW coil wound on a thick, black aluminum former to incredible levels of excursion. The X series was designed from the ground-up to become the new standard in the low-frequency / small ported box subwoofer category in this price range. They will work in anything from our traditional very small enclosures (like the SA and Z v.3 series) up to about 50% larger than those suggestions for the maximum amount of low-frequency extension. The X series is really a different kind of woofer due to it's incredibly linear suspension. They are designed for the LOWEST level of bass extension possible while maintaining low levels of distortion. They are NOT a peaky SPL woofer -- these are true low distortion, high excursion bass transducers! Due to the extremely low level of suspension induced distortion the typical "punchy" upper-bass peak in the 40s-60s Hz range that occurs with traditional woofers when pushed to high excursion does not occur. This "punch" is caused by a tightening of the suspension over stroke leading to increased FS and Qts figures -- in other words it is distortion. In simpler terms -- the X series frequency response does not change much over it's full excursion range provided a consistant and flat response at any volume level. Once you experience and re-listen to all of your favorite music on a low distortion driver you are unlikely to go back! For customers after a more "traditional" sound we are developing a suite of "SPL" cones and spiders. These will retain as much of the high stroke of the stock suspension as possible but will increase the static FS and offer more suspension tightening over stroke. Ask your dealer about this option; which is coming in 2Q-3Q of 2014. Xmax = 30mm one-way by 70% BL RMS Power = 1250-watts

This subwoofer will function just as new and comes with a 30-day guarantee against build defects. INFORMATION BELOW IS TAKEN FROM THE SUNDOWN WEBSITE The X v.2 series is the first driver in the Sundown woofer line-up to offer our "ultra-high excursion" suspension and frame designs. The 10, 12, and 15" models feature our custom tooled and patented frames (US Patent Numbers D691596, D691597, and D691598) and the 18" model uses the tried and true 18" 6-spoke with a custom tooled adapter to allow for a full 10" diameter spider. Optionally our custom tooled 18” frame is available for an extra charge (US Patent Number D741841) – this frame utilizes an 11” spider & changes the coil configuration availability changes to D1 & D2. We mate these new platforms to a triple stacked 220mm (8.66”) diameter motor structure featuring a hyper-extended pole and extreme clearances (allowing up to 4" p-p travel before mechanical bottom). This motor drives a 3" diameter 4-layer CCAW coil wound on a thick aluminum former to incredible levels of excursion. For the v.2 revision we upgraded the coil to a new “black coil” design which handles significantly more heat than the coil form the X v.1 series. The X v.2 series was designed from the ground-up to become the new standard in the low-frequency / small ported box subwoofer category in this price range. They will work in the same small enclosures that you are used to using for Sundown Audio subwoofers, although, the will tolerate enclosures up to about 50% larger than those if you desire even more low-end extension. The X v.2 series is really a different kind of woofer due to its incredibly linear suspension. They are designed for the LOWEST level of bass extension possible in a small enclosure while maintaining extremely low levels of distortion. One of the most obvious changes from the v.1 series is the much larger motor structure (220mm vs. 190mm on the v.1 series). The motor ventilation has also been improved and we also upgraded to the all-new Mega-Roll v.2 surround which is a more linear & more rugged update to our world-famous Mega-Roll v.1 surround design.

DEPENDING ON WHAT MOTOR WE HAVE IN STOCK, YOU MAY END UP WITH A REV1 OR REV2 MOTOR. EITHER WAY, THEY WILL BE BUILT AS YOU PLEASE. PLEASE NOTE REV1 AND REV2 MOTORS WILL WORK WITH EACH OTHER AND LOOK NEARLY IDENTICAL. It will take on average, 2-14 days for a subwoofer to be built and shipped. **Please understand that this is a refurbished subwoofer.** Explanation of a refurbished subwoofer: Sub may have scratches, blemishes and not look 100% brand new since we are re-using a working motor and frame (unless a new frame is requested upon purchase), and installing brand new parts inside i.e. cone, coil, spider, triple joint ring, and dust cap. This subwoofer will function just as new and comes with a 30-day guarantee against build defects. INFORMATION BELOW IS TAKEN FROM THE SUNDOWN WEBSITE The Z v.4 Rev.2 is the second step up in Sundown's "ultra-high excursion" subwoofer lineup. The 10, 12, and 15" models feature Sundown's custom tooled and patented frames (US Patent Numbers D691596, D691597, and D691598) and the 18" model uses the tried and true 18" 6-spoke with a custom tooled adapter to allow for a full 10" diameter spider. Optionally our custom tooled 18” frame is available for an extra charge (US Patent Number D741841) – this frame utilizes an 11” spider. We mate these new platforms to a triple stacked 220mm (8.66”) diameter motor structure featuring a hyper-extended pole and extreme clearances (allowing up to 4" p-p travel before mechanical bottom). Compared to the X v.2 motor both the top & back plates are twice as thick allowing for even more magnetic strength. This motor drives a 3" diameter 8-Layer Flat Wire Aluminum Coil wound on a thick aluminum former to incredible levels of excursion. Starting with the Rev.2 we use 100% American made voice coils & build each unit in-house here in North Carolina. The Z v.4 series was designed from the ground-up to become the new standard in the low-frequency / small ported box subwoofer category in this price range. They will work in the same small enclosures that you are used to using for Sundown Audio subwoofers, although, the will tolerate enclosures up to about 50% larger than those if you desire even more low-end extension. The Z v.4 series is really a different kind of woofer due to its incredibly linear suspension. They are designed for the LOWEST level of bass extension possible in a small enclosure while maintaining extremely low levels of distortion. One of the most obvious changes from the Rev.1 is that the motor ventilation has been significantly improved – we increase the gap venting from 6 vents to 16 vents in order to more evenly spread the air-flow over the coil & also chamfered the vents to increase their air-flow potential. The pole cap was further optimized to provide more aerodynamic flow under the dust-cap. The Rev.2 was additionally upgraded to the all-new Mega-Roll v.2 surround which is a more linear & more rugged update to our world-famous Mega-Roll v.1 surround design.

Refurbished Sundown Z v.5 Subwoofer

It will take on average, 2-14 days for a subwoofer to be built and shipped. **Please understand that this is a refurbished subwoofer.** Explanation of a refurbished subwoofer: Sub may have scratches, blemishes and not look 100% brand new since we are re-using a working motor and frame (unless a new frame is requested upon purchase), and installing brand new parts inside i.e. cone, coil, spider, triple joint ring, and dust cap. This subwoofer will function just as new and comes with a 30-day guarantee against build defects. INFORMATION BELOW IS TAKEN FROM THE SUNDOWN WEBSITE The Z v.5 is the second step up in our "ultra-high excursion" subwoofer lineup after the X v.2 series and replaces the world-famous Z v.4 series. The 10, 12, 15, and 18" models all feature our custom tooled and patented frames (US Patent Numbers D691596, D691597, D691598, and D741841). We mate these new platform frames to a triple stacked 234mm (9.21”) diameter motor structure with a total magnet stack height of 102mm (4.01”) featuring a hyper-extended pole and extreme clearances (allowing over 4" p-p travel before mechanical bottom effectively making it bottomless). Compared to the X v.2 motor both the top & back plates are thicker allowing for even more magnetic strength and excursion potential. This motor drives a 3" diameter 4-Layer Flat Wire Aluminum Coil wound on a thick aluminum former to incredible levels of excursion. The Z v.5 now uses the same voice coil as the NS v.3 series in the stock configuration – which means it is now a much longer 4-layer compared to a shorter 8-layer found in the Z v.4 series. The 4-Layer coil is able to shed heat faster, has a much lower inductance, and has less mass all while allowing for a higher linear excursion and thus significantly less distortion. We leveraged the much larger motor to keep total motor force similar to the Z v.4 Rev.2 while also having all of the other advantages listed prior. We do also offer an optional 8-layer coil that offers a significantly higher motor force factor & thus a lower Qts. Compared to the Z v.4 Rev.2 we also increased the thickness of the Magnet ID shorting ring by 33% to further reduce static inductance and inductive distortion over strong. Based on our years of experience with the Z v.4 series we improved the voice coil ventilation to be even more effective and feature reduced turbulence in order to reduce voice coil temperatures & increase reliability. The Z v.5 series was designed from the ground-up to become the new standard in the low-frequency / small ported box subwoofer category in this price range. They will work in the same small enclosures that you are used to using for Sundown Audio subwoofers, although, the will tolerate enclosures up to about 50% larger than those if you desire even more low-end extension.
