All models (12,15,18) feature our custom tooled and patented frames (US Patent Numbers D691597, D691598, and D741841) – the Sundown “mega-platform.” Please note – the Z v.7 is not available, aside from special orders, in 10s due to the motor size.\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"elementToProof\"\u003eWe mate these new platform frames to a quad stacked 265mm (10.43”) diameter motor structure with a total magnet stack height of 100mm (3.94”) featuring a hyper-extended pole and extreme clearances (allowing over 4\" p-p travel before mechanical bottom effectively making it bottomless). This is, by far, the largest motor we have ever produced on a Z series sub-woofer. The motor force factor (BL^2\/RE) is ~50% higher than the previous generation Z v.6 series.\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"elementToProof\"\u003eThis motor drives a 3.3\" diameter 4-Layer Round Wire Aluminum Voice Coil wound on a thick aluminum former. These new round wire coils use a special Sundown designed “fat wire” winding method to handle significant amounts of power and abuse.\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"elementToProof\"\u003eBased on Sundown's years of experience with the Z v.4, 5, and 6 series we've also improved the voice coil ventilation yet again. The Z v.7 features an entirely new and patent-pending airflow directing pole cap, six pole OD channels, SIXTEEN gap vents, and a cross-drilled \/ slotted top plate to keep the voice coil running cool under extreme conditions.\u003cbr\u003e\u003cbr\u003eThe Z v.7 motor also features a 9mm thick magnet ID Faraday ring which is locked into both the top and back plates. This ring combined with an all-new pole-extension inductance sleeve gives the Z v.7 the most linear inductive performance of any mega-platform sub-woofer to date. As if all of this were not enough to cement the Z v.7as a legend... we were also able to achieve 42mm of one-way linear excursion by 70% BL with an extremely uniform curve via our extensively FEA optimized motor and 95mm long voice-coil winding length.\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"elementToProof\"\u003eThe Z v.7 series was designed from the ground-up to become the new standard in the low-frequency \/ small, ported box sub-woofer category in this price range. They will work in the same enclosures that are commonly used for Sundown Audio's mega-platform sub-woofers.\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"elementToProof\"\u003eThe Z v.7 series, like its other mega-platform brethren, 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.\u003cbr\u003e\u003cbr\u003e\u003cspan\u003e\u003cstrong\u003ePhysical Dimensions:\u003c\/strong\u003e \u003ca rel=\"noopener\" title=\"ZV7-15\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/files\/Zv7-15_thin.pdf?v=1765992345\" target=\"_blank\"\u003eDownload\u003c\/a\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e","brand":"Sundown Audio","offers":[{"title":"Default Title","offer_id":52877036290159,"sku":"SW-ZV715D1","price":1364.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0713\/0519\/9727\/files\/ZV7CoverImage_63a3c756-a41d-4d2f-8cfa-0d8729a5ffa4.png?v=1775008482","url":"https:\/\/caraudiobargain.com\/products\/z-series-zv7-15-subwoofer-dual-1-ohm","provider":"Car Audio Bargain","version":"1.0","type":"link"}
