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":"Default Title","offer_id":52877023281263,"sku":"SW-UV110D4","price":499.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0713\/0519\/9727\/files\/U-10-000_8269fb78-5a35-4701-b4c6-99ba5184e522.png?v=1775008072","url":"https:\/\/caraudiobargain.com\/products\/sundown-audio-u-series-v-1-10-subwoofer-dual-4-ohm","provider":"Car Audio Bargain","version":"1.0","type":"link"}
