It comes with a non-doa warranty only. That means they are guaranteed to work when you receive it but no further warranty afterwards. Let us know within 24 hours of delivery if this product has an issue. We will not warranty any used subwoofer after that time. These potentially have scratches \u0026amp; scuffs on the magnets\/motors and will not be in new condition.\u003c\/span\u003e\u003c\/p\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. 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

Introducing the “Sundown Full Bridge” line of amplifiers, “SFB” for short. These amps pack a huge punch in a fairly small footprint. Due to the full bridge technology, these amplifiers are not strappable however you can line up multiple amps together to create a massive powerhouse in the same, if not smaller, footprint of your standard half bridge predecessors for a fraction of the cost.\u003c\/p\u003e\n\u003cp style=\"font-weight: 400;\"\u003eAll of the SFB 4ch amp’s power ratings are listed at the 1ohm rating. For instance, the SFB-500.4 is 500Wrms at 1ohm per channel. This allows you to run many more speakers together in a multitude of different wiring configurations than using a standard Class A\/B\/D half bridge design. These are the perfect amplifiers for large systems where you have a plethora of pro drivers in multiple doors or line arrays.\u003c\/p\u003e\n\u003cp style=\"font-weight: 400;\"\u003eAll SFB mono amplifiers are full range. This not only allows you to run subwoofers as you would most mono amps, but you can also run a large arrays of mids\/highs on these amps as well. The crossovers on the mono SFB amps can attenuate from 15hz all the way up to 20khz. This allows you to set bandpass crossover points and dial in whatever frequency you desire for your setup no matter the type of speaker you are using.\u003c\/p\u003e\n\u003cp style=\"font-weight: 400;\"\u003eThe SFB series amps are considered to be a “Brazilian Style” of amplifier. This technology is not new and has been around for quite a while however, the use of them has surged dramatically in the past few years. These little amplifiers are known to be the best bang for your buck. If you are looking for raw power on a budget, look no further than the SFB Series from Sundown Audio.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/files\/SFB-Amp-Manual.pdf?v=1688793255\"\u003eProduct Manual\u003c\/a\u003e \u003cmeta charset=\"UTF-8\"\u003e\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\" data-mce-fragment=\"1\"\u003eFeatures\u003c\/h3\u003e\n\u003cdiv class=\"el-content uk-panel uk-margin-top\" data-mce-fragment=\"1\"\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eDigital Class-D Mono Block Amplifier\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eDual MOS-FET PWM Power Supply\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e1 Ohm Stable Load\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e12 dB\/Octave – Variable Low Pass Filter\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e12 dB\/Octave – Variable High Pass Filter\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e9 dB\/Octave – Variable Bass Boost\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e4 Way Protection Ciruit (Thermal, Voltage, Speaker Short, DC Offset)\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"box-2\"\u003e\n\u003ch3 class=\"el-title uk-text-danger uk-margin-top uk-margin-remove-bottom\" data-mce-fragment=\"1\"\u003eSpecifications\u003c\/h3\u003e\n\u003cdiv class=\"el-content uk-panel uk-margin-top\" data-mce-fragment=\"1\"\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003e1 ohm Mono RMS 5000W\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e2 ohm Mono RMS 3200W\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e4 ohm Mono RMS 2200W\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eRecommended Fuse Rating 220A x 2\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eLow Pass Filter (Variable) 80Hz-20kHz\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eHigh Pass Filter (Variable) 15Hz-80Hz\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eBass Boost @ 50Hz 0-12dB\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eInput Sensitivity 5V Max\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eS\/N Ratio 100dB\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eWorking Voltage 10.5v-15.5v\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eDimensions 9.00\" x 11.50\" x 2.75\"\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":53064547893558,"sku":"RA-SFB5000D","price":319.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/products\/sundown-audio-sfb-5000d-5000w-full-range-car-audio-amplifieramp-759544.png?v=1689636963"},{"product_id":"stereo-integrity-siq-200-2-high-fidelity-2-channel-amplifier-200w-rms-x2-4ω-class-a-b-audiophile-design-full-bandwidth-5hz-150khz-zero-filters-crossovers-eq-amplifier","title":"Stereo Integrity SIQ 200.2 High-Fidelity 2-Channel Amplifier","description":"\u003ch3\u003e\u003cstrong\u003eStereo Integrity SIQ 200.2 Amplifier: Purity and Power in Two Channels\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eStereo Integrity SIQ 200.2\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ebrings true high-fidelity audio engineering back to mobile sound systems.

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. 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\u003cul class=\"uk-list\"\u003e\n\u003cli\u003e\n\u003cspan\u003eBlack Aluminum 3” voice coil former for superior heat dissipation\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eHigh Temperature Round-Wire CCAW voice coil with high-temp black adhesive\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eDouble stitched surround\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eHeavy duty cast basket\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eSpring loaded terminals accept up to 8 gauge\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eStitched-on double-XL tinsel leads\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eRear vented pole piece\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eRear drilled gap-venting\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eInnovative high-velocity cast aluminum vented frame spacer ring\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eMagnet ID shorting ring\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eTop-Plate Cooling Channels\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eCast Aluminum surround bolt-on rings\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eOptimized for small ported or bandpass enclosures\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul id=\"js-3eb\" class=\"uk-switcher\"\u003e\u003c\/ul\u003e","brand":"Sundown Audio","offers":[{"title":"Dual 2 Ohm","offer_id":53874017763638,"sku":"USW-UV110D2","price":399.99,"currency_code":"USD","in_stock":true},{"title":"Dual 4 Ohm","offer_id":53874017796406,"sku":"USW-UV110D4","price":399.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/files\/U-10-000_8269fb78-5a35-4701-b4c6-99ba5184e522.png?v=1695062046"},{"product_id":"sml-series-8-thin-subwoofer-used","title":"Used SML-Series 8\" Thin Subwoofer","description":"\u003cdiv data-mce-fragment=\"1\" class=\"uk-panel uk-margin\"\u003e\n\u003cul\u003e\n\u003cli\u003e400 Watts RMS\/800 Watts Peak\u003c\/li\u003e\n\u003cli\u003eDual 2 or 4 ohm voice coils\u003c\/li\u003e\n\u003cli\u003eBlack Aluminum 2.25” voice coil former for superior heat dissipation\u003c\/li\u003e\n\u003cli\u003eHigh temperature 4-layer copper voice coil wire\u003c\/li\u003e\n\u003cli\u003eStitched-on “Mini-XL” tinsel Leads to prevent fatigue and failure\u003c\/li\u003e\n\u003cli\u003eVented pole-piece and vented magnetic gap\u003c\/li\u003e\n\u003cli\u003eDual-magnet design for smooth acoustic response\u003c\/li\u003e\n\u003cli\u003eCustom tooled cone shape for reduced mechanical noise over high excursion\u003c\/li\u003e\n\u003cli\u003eBolt-through motor design to ensure maximum longevity and ruggedness \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"MsoNormal\" style=\"line-height: normal;\"\u003eThe SML series is a revolutionary line of subwoofers offered by Sundown Audio.

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.
