A double-stacked 9.4-inch wide ferrite magnet system is coupled to a thick top plate. A thick set of shorting rings are used inside the magnets and on the pole cap, smoothing out frequency response while doubling as a heat sink and airflow guide. A custom aluminum frame was designed specifically for the U Series. It’s substantially thicker and equipped with heat dissipation ribs at the bottom of the frame. The U v.2 motor also features an extended pole piece to keep the coil under perfect control under high stress. The coil temperature is controlled with machined, high-velocity pole channels and a series of 16 direct air-gap vents in the back plate.\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv

A thick set of shorting rings are used inside the magnets and on the pole cap, smoothing out frequency response while doubling as a heat sink and airflow guide. A custom aluminum frame was designed specifically for the U Series. It’s substantially thicker and equipped with heat dissipation ribs at the bottom of the frame. The U v.2 motor also features an extended pole piece to keep the coil under perfect control under high stress. The coil temperature is controlled with machined, high-velocity pole channels and a series of 16 direct air-gap vents in the back plate.\u003c\/p\u003e\n\u003cdiv class=\"cus-flex\"\u003e\n\u003cdiv

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.\u003c\/p\u003e\n\u003cp\u003eWe 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eIf 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.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul class=\"uk-list\"\u003e\n\u003cli class=\"element element-textarea\"\u003eBlack Aluminum 3” voice coil former for

A double-stacked 9.4-inch wide ferrite magnet system is coupled to a thick top plate. A thick set of shorting rings are used inside the magnets and on the pole cap, smoothing out frequency response while doubling as a heat sink and airflow guide. A custom, substantially thicker aluminum frame was designed specifically for the U Series, equipped with heat dissipation ribs. The U v.2 motor also features an extended pole piece to keep the coil under perfect control under high stress. The coil temperature is kept in check via a high-velocity solid pole \/ machined pole channels arrangement and a series of 16 direct air-gap vents in the back plate.\u003c\/p\u003e\n\u003cdiv class=\"cus-flex\"\u003e\n\u003cdiv class=\"box-2\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"box-4\"\u003e\n\u003ch3\u003eDimensions\u003cbr\u003e\n\u003c\/h3\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/files\/U-12_v2.pdf_1.jpg?v=1699971870\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cul id=\"js-75b\" class=\"uk-switcher\" data-mce-fragment=\"1\"\u003e\u003c\/ul\u003e","brand":"Sundown Audio","offers":[{"title":"D4","offer_id":53873951965494,"sku":"USW-UV212D4","price":400.99,"currency_code":"USD","in_stock":true},{"title":"D2","offer_id":53873951998262,"sku":"USW-UV212D2","price":400.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/files\/Uv2-12-000-3b077488.png?v=1696604217"},{"product_id":"sundown-audio-u-series-v-1-10-subwoofer-used","title":"Used Sundown Audio U-Series v.1 10\" Subwoofer","description":"\u003cdiv\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eWe 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eIf 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.

The entire motor would need to be nearly 250 degrees F before the magnet is affected in any way. This is nearly 40 degrees more than is required to boil water! There are many myths surrounding Neo motors – and none of these apply to the Nightshade.\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eThe Neo magnets are sandwiched between two aluminum plates which meet the air gap along their inner edge. These plates help carry the heat away from the gap and thus the magnets and voice coil. The bottom aluminum plate is cooled by the air going in and out of the holes around the motor. The top aluminum plate is cooled by the air-flow from the spider going in and out of vented spacer ring. These plates also serve as very effective shorting rings. Furthermore, the Neo magnets themselves do not directly come into contact with the “air gap” of the woofer like most Neo-Radial designs; meaning they will never be directly adjacent to the extremely hot voice coil. Instead, a flux distribution ring separates them from the magnetic gap (see patent). Coming from the NS v.4 to the v.5 the bottom ring was expanded all the way down the cylinder ID into a full-length shorting ring (a total of over 2 lbs of aluminum). All of this thermally conductive material in proximity to the coil serves to pull heat away from the gap.\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eSince we are talking about shorting rings – we are talking about inductance and, thus, inductive distortion. It represents the lowest % of distortion in a bass speaker but, arguably, the most objectionable (being odd order). This lower ring extends down inside of the main steel casing. It's main job in terms of LE is to reduce the LE as the coils moves down -- to even out the LE curve so it's even forward to backward. When the coil moves forward it is moving away from the big \"iron\" core (pole piece) so LE goes down (less of the coil is wrapped around the pole). As the coil moves backward it is getting more of an \"iron\" core so LE goes up. By adding this huge shorting ring below the magnet casing inside the motor we ensure that LE goes down at a similar rate in both directions.\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eThat brings us to the vent ring itself (mounted between the frame and the motor). For the NS v.4\/v.5 we developed and tooled solid cast aluminum vent rings. Thus allowing heat to more easily move through the aluminum “top plate” and into the vent ring and thus finally into the frame itself. Our “Sundown” frames are MASSIVE chunks of aluminum (e.g. Heat-Sinks) with the 18” frame being a full 10 pounds of metal!\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eNow let’s discuss the “active” cooling of the coil. As most people are aware a solid pole piece necessarily forces all of the air under the dust cap across the former as the woofer moves back and forth thus resulting in quick heat dissipation from the aluminum former. This air can then easily escape the side vent-holes of the motor and be exchanged with cooler air. Additionally; the “Sundown” frames features a “closed base” design which forces all the air movement from the spider to go through the vent ring creating a high velocity air stream across the top part of the coil. This type of cooling is used on everything we make from the SA series on up and has proven incredibly effective since we began using this method over a decade ago. For the NS v.5 we added four vent channels around the pole to help relieve just enough pressure to keep the dust-cap intact under extreme conditions.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp data-mce-fragment=\"1\"\u003eAs with all Sundown Audio products we set out to create something genuinely different with the Nightshade v.5 woofers.

All models (10,12,15,18) feature our custom tooled and patented frames (US Patent Numbers D691596, D691597, D691598, and D741841). Our proprietary frames allow 4” or more of peak-to-peak mechanical excursion.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eFrom here the NS (Nightshade) line diverges dramatically from our other lines. The motor is based on our patented S.A.I.N.T. (Sundown Audio Intelligent Neodymium Technology) Design (US Patent Numbers US10382874B2 and USD791740S1). As of the release of the NS v.4\/v.5 series these are the only products in our line to utilize this all new and proprietary design.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe Nightshade v.5 features an enormous 45mm (1.77”) magnetic gap to ensure the coil is always under control. This motor drives a 3\" diameter 8-Layer Flat Wire Aluminum Coil with an extremely long winding (3.15” long) wound on a thick aluminum former to incredible levels of excursion.\u003c\/p\u003e\n\u003cdiv class=\"uk-panel uk-margin\" data-mce-fragment=\"1\"\u003e\n\u003cp data-mce-fragment=\"1\"\u003eWith the introduction of the new light-weight motors we also incorporated several new cooling \/ thermal management features to push the power handling up to an enormous 3000-watts RMS:\u003c\/p\u003e\n\u003col data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eThe motor utilizes N52H Neo (heat treated). The entire motor would need to be nearly 250 degrees F before the magnet is affected in any way. This is nearly 40 degrees more than is required to boil water! There are many myths surrounding Neo motors – and none of these apply to the Nightshade.\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eThe Neo magnets are sandwiched between two aluminum plates which meet the air gap along their inner edge. These plates help carry the heat away from the gap and thus the magnets and voice coil. The bottom aluminum plate is cooled by the air going in and out of the holes around the motor. The top aluminum plate is cooled by the air-flow from the spider going in and out of vented spacer ring. These plates also serve as very effective shorting rings. Furthermore, the Neo magnets themselves do not directly come into contact with the “air gap” of the woofer like most Neo-Radial designs; meaning they will never be directly adjacent to the extremely hot voice coil. Instead, a flux distribution ring separates them from the magnetic gap (see patent). Coming from the NS v.4 to the v.5 the bottom ring was expanded all the way down the cylinder ID into a full-length shorting ring (a total of over 2 lbs of aluminum). All of this thermally conductive material in proximity to the coil serves to pull heat away from the gap.\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eSince we are talking about shorting rings – we are talking about inductance and, thus, inductive distortion. It represents the lowest % of distortion in a bass speaker but, arguably, the most objectionable (being odd order). This lower ring extends down inside of the main steel casing. It's main job in terms of LE is to reduce the LE as the coils moves down -- to even out the LE curve so it's even forward to backward. When the coil moves forward it is moving away from the big \"iron\" core (pole piece) so LE goes down (less of the coil is wrapped around the pole). As the coil moves backward it is getting more of an \"iron\" core so LE goes up. By adding this huge shorting ring below the magnet casing inside the motor we ensure that LE goes down at a similar rate in both directions.\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eThat brings us to the vent ring itself (mounted between the frame and the motor). For the NS v.4\/v.5 we developed and tooled solid cast aluminum vent rings. Thus allowing heat to more easily move through the aluminum “top plate” and into the vent ring and thus finally into the frame itself. Our “Sundown” frames are MASSIVE chunks of aluminum (e.g. Heat-Sinks) with the 18” frame being a full 10 pounds of metal!\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eNow let’s discuss the “active” cooling of the coil. As most people are aware a solid pole piece necessarily forces all of the air under the dust cap across the former as the woofer moves back and forth thus resulting in quick heat dissipation from the aluminum former. This air can then easily escape the side vent-holes of the motor and be exchanged with cooler air. Additionally; the “Sundown” frames features a “closed base” design which forces all the air movement from the spider to go through the vent ring creating a high velocity air stream across the top part of the coil. This type of cooling is used on everything we make from the SA series on up and has proven incredibly effective since we began using this method over a decade ago. For the NS v.5 we added four vent channels around the pole to help relieve just enough pressure to keep the dust-cap intact under extreme conditions.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp data-mce-fragment=\"1\"\u003eAs with all Sundown Audio products we set out to create something genuinely different with the Nightshade v.5 woofers. We weren't content with simply rehashing existing Neo motor designs. We started from the get-go with our own proprietary, patented topology to achieve the maximum possible performance at a much more reasonable weight (NS v.4\/v.5 are over 30 lbs lighter than the v.3).\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe NS v.5 series was designed from the ground-up to become the new standard in the low-frequency \/ small ported box sub-woofer category.

Its motor geometry allows for a remarkable 14mm one-way linear Xmax, delivering excursion equivalent to far larger cones.\u003c\/p\u003e\n\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/files\/E-12_v.4.pdf?v=1694533031\"\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/a\u003e\n\u003c\/div\u003e","brand":"Sundown Audio","offers":[{"title":"D4","offer_id":53880843141430,"sku":"USW-EV415D4","price":156.99,"currency_code":"USD","in_stock":true},{"title":"D2","offer_id":53880843174198,"sku":"USW-EV415D2","price":156.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/products\/e-series-v4-15-500w-subwoofer-417146.png?v=1689636895"},{"product_id":"sa-6-5cs-v-3-6-5-6-1-2-component-car-audio-speakers-tweeters-used","title":"Used Sundown Audio SA6.5CSV3SET Speaker","description":"\u003cp\u003e \u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eWhen Sundown set out to design the \"SA\" series component they knew it had to be something special; something to uphold the reputation of the SA series subwoofer line. But at the same time the price had to remain reasonable; something that almost anyone can afford.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe SA component set starts out with its custom designed midrange driver. The mid features a high quality cast aluminum basket as its starting point; where many speakers in this category go with cheaper stamped steel frames. \u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe cone is a carefully selected blend of paper and wool fibers designed to damp any unwanted resonances. The dust cap is a soft poly whose size, shape, and material were all chosen to create the least amount of breakup and distortion as possible. The surround is a very compliant rubber that helps to tame any remaining edge resonances within the cone. With any midrange the cone, surround, and dust cap are CRITICAL to the sound. When designing the SA set we had no concern for fancy cosmetics or other \"audio jewelry\" \u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe motor was FEA optimized in-house to increase linear excursion and features a full 6mm one-way linear excursion thanks to a carefully designed motor and extended pole piece. We also thoroughly considered thermal performance in the design with the SA mid featuring a vented magnetic gap and a vented voice coil collar. The 60-watt per side power rating on the SA mid is derived from a full 8-hour test on pink noise (full bandwidth down to 20 Hz) -- so when crossed over on the bottom-end this figure ends up being VERY conservative. Most customers use 100+ watt RMS amplifiers on the SA sets. \u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe SA series tweeter had to match the smooth sound of the midrange so we went with a silk dome. We tested numerous versions, tweaked the gap, dome material, tested various lenses, various chamber damping materials, so on and so forth until arriving at the final design. As the response graph is proof of the result is an incredibly smooth sounding tweeter. Don't be fooled by the simple housing -- as we are all taught not to judge a book by its cover and you will find this tweeter performs as good or better than many fancier looking counterparts. We stuck with the Sundown mentality of not spending money where it doesn't increase performance. \u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe crossover is also relatively simple looking at first glance but it does the job perfectly. It is a 12 dB network centered at 3800 Hz with high quality air core inductors and Mylar capacitors. It also features the ability to change the LPF on the mid from a 12dB, to 6dB, to a bypassed slope as well as to adjust the tweeter from 0, to -3, to -6 dB levels. \u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eWe are confident that anyone who is after a smooth sounding set will be incredibly pleased with the SA component line. Reviews have been overwhelmingly positive on them from all over the globe. If you are a metal or hard dome tweeter fan it may not be your set but we will develop a \"sharper\" sounding set down the line! \u003c\/p\u003e\n\u003cdiv class=\"cus-flex\"\u003e\n\u003cdiv class=\"box-1\"\u003e\n\u003ch3 class=\"el-title uk-text-danger uk-margin-top uk-margin-remove-bottom\"\u003eFeatures \u0026amp; Specifications\u003c\/h3\u003e\n\u003cdiv class=\"el-content uk-panel uk-margin-top\"\u003e\n\u003cul\u003e\n\u003cli\u003e6.5\" Component Speakers System\u003c\/li\u003e\n\u003cli\u003e125 Watts \/ Side\u003c\/li\u003e\n\u003cli\u003eSilk Dome Tweeter\u003c\/li\u003e\n\u003cli\u003eMachine Aluminum Tweeter Housing\u003c\/li\u003e\n\u003cli\u003eCase Aluminum Frame\u003c\/li\u003e\n\u003cli\u003eMagnet ID Shorting Ring (Midrange)\u003c\/li\u003e\n\u003cli\u003eCarbon Fiber Cone\u003c\/li\u003e\n\u003cli\u003eRubber Surround\u003c\/li\u003e\n\u003cli\u003e24dB\/Octave Crossover\u003c\/li\u003e\n\u003cli\u003eAdjustable Tweeter Level (-3, 0, +3)\u003c\/li\u003e\n\u003cli\u003eMounting Depth: 2.87\"\u003c\/li\u003e\n\u003cli\u003eCutout: 5.63\"\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Sundown Audio","offers":[{"title":"Default Title","offer_id":53881072648502,"sku":"US-SA6.5CSV3SET","price":260.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/products\/sa-65cs-v3-65-6-12-component-car-audio-speakerstweeters-260572.png?v=1689636904"},{"product_id":"z-series-zv7-18-subwoofer-used","title":"Used Z-Series ZV7 18\" Subwoofer","description":"\u003cdiv class=\"elementToProof\"\u003eThe Z v.7 is the third step up in Sundown's 2025 \"ultra-high excursion\" sub-woofer lineup after the M and X v.4 series.

We stuck with the 2.75” coil diameter and added another 5mm of length for additional linear x-max (22mm now). We are able to perfectly balance the mass, motor force, and suspension stiffness for the intended power level. Compared to the v.2 the v.3 features taller cones and wider spiders to enhanced linearity and coil stability to the next level. We also utilized full 3D FEA to further optimize the spider packs for this generation.\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"elementToProof\"\u003eThe motor also features a large magnet shorting ring (faraday ring) \u0026amp; pole cap faraday ring to reduce distortion and deliver smoother response across the entire acoustic spectrum. With the v.3 upgrade we integrated a completely \"locked-in\" faraday ring that is physically held in place by the T-Yoke. The motor \u0026amp; coil setup is mated to an extremely robust multi-layer spider with fully tied-on \u0026amp; doubled-up “XL” tinsel leads. A competition-grade paper cone, strong foam surround, and custom-tooled aluminum frame (same frame as the bigger brother U v.2 series) are used to complete this masterpiece. On top of the ~22mm of one-way linear excursion we have an x-mech limit of 41mm one-way before coil bottom making it nearly \"bottomless.\" The new motor was designed as a \"little brother\" to the U v.2 series so you will also note the updated venting system with a solid pole piece from the back and channeled pole on the inside.\u003c\/div\u003e\n\u003cdiv class=\"box-4\"\u003e\n\u003ch3\u003eEnclosure Designs\u003cbr\u003e\n\u003c\/h3\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/files\/E-SA-SAv2-U-12in-Single-Information_560e73e2-e0f0-4e8f-ae4a-7d2c8f128de6.jpg?v=1688789558\"\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/files\/E-SA-SAv2-U-12in-Single-0_c2a5a2bb-8450-4043-888a-f7cebce726ee.jpg?v=1688789564\"\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/files\/E-SA-SAv2-U-12in-Single-1_50b4c5b5-5ca2-40f8-84e6-ae9958753929.jpg?v=1688789562\"\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/files\/E-SA-SAv2-U-12in-Single-2_41f99599-339b-4e97-a026-c562e4a43230.jpg?v=1688789559\" alt=\"\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/files\/E-SA-SAv2-U-12in-Single-3_27d64631-b6c4-4c25-92b6-02f2cedeef56.jpg?v=1688789560\"\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/files\/E-SA-SAv2-U-12in-Single-Cutsheet_97348127-2692-4e07-a124-1142030b6d8d.png?v=1688789558\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/files\/E-SA-SAv2-U-12in-Single_4c94560c-24a5-4f94-8d6b-38216439b417.zip?v=1688789586\"\u003e.Zip File\u003c\/a\u003e\n\u003c\/div\u003e","brand":"Sundown Audio","offers":[{"title":"D4","offer_id":53883598733622,"sku":"USW-SAV312D4","price":287.66,"currency_code":"USD","in_stock":true},{"title":"D2","offer_id":53883598766390,"sku":"USW-SAV312D2","price":287.66,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/files\/SAv31215_cebd6c5f-0ffe-4b1f-946d-736d99192053.png?v=1739370203"},{"product_id":"bps-6-5-6-5-pro-sound-co-axial-powersports-speaker-used","title":"BPS-6.5 6.5\" Pro Sound Co-Axial Powersports Speaker *USED*","description":"\u003cul data-mce-fragment=\"1\" style=\"box-sizing: border-box;
