The unit features a 3\" 'sandwich' inside and outside windings voice coil, driven by a non-inductive motor system which dramatically reduces third harmonics and intermodulation distortion. The cone membrane, manufactured from polycellulose, is much stronger and more durable than conventional paper alternatives. This allows the driver to combine high sensitivity with the structural integrity required to produce undistorted low frequencies at high output levels. The mechanical and electrical properties of the unit have been carefully optimised to allow extended low frequency output up to its rated power handling of 500W (AES). The driver is best used in ported enclosures of 25 to 80 litres.\u003c\/strong\u003e\u003c\/p\u003e\u003c\/div\u003e\u003cdiv class=\"features\"\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOptimised non-inductive motor system efficiently controls magnetic flux and reduces third-harmonic and intermodulation distortion\u003c\/li\u003e\n\u003cli\u003eFast and dynamic driver producing punchy bass\u003c\/li\u003e\n\u003cli\u003eUK manufactured cone with optimised pulp offering increased strength, durability and performance\u003c\/li\u003e\n\u003cli\u003ePerforms best in ported enclosures of 25 to 80L capacity\u003c\/li\u003e\n\u003cli\u003e3\" Copper voice coil\u003c\/li\u003e\n\u003cli\u003eMagnet material: Ferrite\u003c\/li\u003e\n\u003cli\u003ePaper cone \u0026amp; dust dome\u003c\/li\u003e\n\u003cli\u003eFrequency response: 40Hz to 3.5kHz\u003c\/li\u003e\n\u003cli\u003eBaffle hole diameter:11.03\"\u003c\/li\u003e\n\u003cli\u003eChassis: Die-cast Aluminium\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eConnectors : Push-button spring terminals\u003c\/li\u003e\n\u003cli\u003eOutput power: 2000W peak\u003c\/li\u003e\n\u003cli\u003eEBP: 165.17Hz (suitable for bass reflex and horn speakers)\u003c\/li\u003e\n\u003cli\u003eDimensions (DxDia): 132x330mmØ\u003c\/li\u003e\n\u003cli\u003eWeight: 7.8kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003cbr\u003e\u003cdiv align=\"center\" class=\"datagrid\"\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cspan\u003eSpecifications\u003c\/span\u003e\u003c\/th\u003e\n\u003cth\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"rowheading\"\u003eDriver Type\u003c\/td\u003e\n\u003ctd\u003eWoofer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"rowheading\"\u003eExternal Diameter - Metric\u003c\/td\u003e\n\u003ctd\u003e330mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"rowheading\"\u003eImpedance\u003c\/td\u003e\n\u003ctd\u003e8ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"rowheading\"\u003ePower Rating Nom\u003c\/td\u003e\n\u003ctd\u003e1kW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"rowheading\"\u003eSound Level SPL\u003c\/td\u003e\n\u003ctd\u003e98dBA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"rowheading\"\u003eFrequency Response Min\u003c\/td\u003e\n\u003ctd\u003e40Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"rowheading\"\u003eFrequency Response Max\u003c\/td\u003e\n\u003ctd\u003e3.5kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"rowheading\"\u003eSpeaker Shape\u003c\/td\u003e\n\u003ctd\u003eRound\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"rowheading\"\u003eResonant Frequency\u003c\/td\u003e\n\u003ctd\u003e55Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"rowheading\"\u003eSpeaker Mounting\u003c\/td\u003e\n\u003ctd\u003eThrough Hole\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"rowheading\"\u003ePower Rating Max\u003c\/td\u003e\n\u003ctd\u003e2kW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"rowheading\"\u003eExternal Depth - Metric\u003c\/td\u003e\n\u003ctd\u003e132mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"rowheading\"\u003eProduct Range\u003c\/td\u003e\n\u003ctd\u003eFane Mid-Bass Drivers 8R\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"rowheading\"\u003eCountry of Origin:\u003c\/td\u003e\n\u003ctd\u003eChina\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003cbr\u003e","brand":"Rapidwarehouse","offers":[{"title":"Default Title","offer_id":48108397461769,"sku":"GGBOB393512-RWWS-","price":158.29,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0740\/1747\/2777\/files\/rwc_img_coming_soon_d47fd11c-18cb-4c2e-8fa7-3cc7c300657d.jpg?v=1720195394","url":"https:\/\/www.rapidwarehouse.com\/products\/12-500w-mid-bass-range-driver-8r-12mb","provider":"Rapidwarehouse","version":"1.0","type":"link"}
