Stay tuned for more updates! This will be our new series to bridge the gap from the SA to the X v.2 series -- it is also the most direct replacement for the discontinued Z v.3 series but at a much lower price. They use the same voice coil as the X v.2 series; therefore RMS power is 1500-watts rated conservatively. The motor is a similar design to the X v.2 series with one less magnet slug since it isn't needed for use on these frames \u0026amp; soft parts. It also retains a magnet ID shorting ring just like the X v.2 series motor. I have tooled 4 new cone bodies \u0026amp; surrounds to mate up to an entirely different frame tooling from the 1st prototypes. These surrounds are based on the Z v.3 18\" surround geometry as this has been our go-to cone for SPL (we use those cones in our Terra for our World Record in SS 3-4 class). We also have tooled the cones to support the same wide-flange dust caps we use on all the new platform drivers. They also feature custom tooled cast aluminum vent spacers to mate up correctly to these frames. We tooled 2 different spacers for this line. Another new feature (also fully custom tooled) is the cast aluminum surround bolt-on ring. We tooled one for each size U series. These woofers will have a similar sound to the Z v.3 series -- meaning they do not have the \"new platform\" sound of the X, Z, NS, etc.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"sundown audio","offers":[{"title":"Default Title","offer_id":42680681365552,"sku":null,"price":569.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0629\/7033\/1184\/files\/600.jpg?v=1767220762","url":"https:\/\/fuegobassshop.com\/products\/copy-of-sundown-audio-u-12-v2-d4-12-1750w-dual-4-ohm-u-series-subwoofer","provider":"Fuego Bass Shop","version":"1.0","type":"link"}
