It uses DD Audio’s largest ferrite motor and is made for competitors and bass lovers who want big output with real control. With 3200W RMS and bursts up to 9600W peak, the 9900C brings power, precision, and durability. It includes the Dual Stage Heat Sink, USA-made Iron Cloth Spider System, and 2nd Gen V-ROM surround for performance and long life. The handcrafted, carbon fiber-loaded pulp cone keeps weight down while staying strong, and the Free Flow Cooling System helps pull heat out of the motor during long sessions.\u003c\/p\u003e\u003cbr\u003e\n\u003cp\u003e\u003cbr\u003e\u003cbr\u003e\nThis is the SuperCharged version. DD adds a specially shaped neodymium ring inside the motor that redirects magnetic energy into the voice coil gap, raising usable motor strength by about 20 to 25%. That means a tighter grip on the cone and cleaner, more controlled bass across the whole power range. Power handling stays the same as the standard 9912C, so plan your amp around 3200 watts RMS.\u003c\/p\u003e\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\n\u003cul\u003e\n\u003cbr\u003e\n  \u003cli\u003eSuperCharged Motor with Neodymium Flux Ring\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eNEW Aluminum 2 Stage Motor Heatsink\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003e260mm Magnet Diameter\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eMulti-Vent Free Flow Cooling Motor\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eShorting Ring Motor\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003e4.3\" High-Temp Voice Coil\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eExcursion Optimized ESP Frame\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eV-ROM Vario-Density Surround\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eNon-Pressed Composite Reinforced Pulp Cone\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003e11\" Dual\/Triple Layer Iron Cloth Spider\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eLaminated Tinsel Leads\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eHand Laid Composite Dust Cap\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eEmbossed DDesign Magnet Boot\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eMade In USA\u003c\/li\u003e\n\u003cbr\u003e\n\u003c\/ul\u003e\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\n\u003cul\u003e\n\u003cbr\u003e\n  \u003cli\u003eSpeaker Size: 12 inches\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eWatts RMS: 3200 (same as standard model)\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eWatts Peak: 9600\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eImpedance: Dual 1-ohm\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eVoice Coil Diameter (VCD): 4 inches\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003ePiston Diameter: 11 inches\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eResonant Frequency (Fs): 31.63 Hz\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eQms: 5.398\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eQes: 0.377 (standard model)\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eQts: 0.352 (standard model)\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eVas: 23.63 liters\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eXmech (Max Excursion): 62 mm\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eXmax (Linear Excursion): 22 mm\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eFrame Outer Diameter (OD): 13.38 inches\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eFrame OD with Gasket: 13.5 inches\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eMounting Diameter: 12.19 inches\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eMounting Depth: 9.69 inches\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eMotor Diameter: 10.31 inches\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eMotor Depth: 4.56 inches\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eWoofer Displacement: 0.33 cu. ft.\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eRecommended Ported Enclosure: 1.75 - 2.75 cu. ft.\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eShipping Weight: 81 lbs\u003c\/li\u003e\n\u003cbr\u003e\n\u003c\/ul\u003e\u003cbr\u003e\n\u003cp\u003eIf you want the biggest 9900 motor with even more control over every hit, the SuperCharged 9912C is the one to grab.\u003c\/p\u003e","brand":"DD Audio","offers":[{"title":"Default Title","offer_id":67971963420920,"sku":"DD-9912C-D1-SC","price":979.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0029\/9384\/8365\/files\/f12874b2782d0ab02a837fd354d12412140ae16cda2602447564fedd7e1bfde0_b77b97fb-2c2d-4f4a-bea5-be9939b3ac6b.jpg?v=1793801760","url":"https:\/\/bigjeffaudio.com\/products\/dd-audio-9912c-d1-supercharged-12-3200w-rms-dual-1-ohm-usa-built-subwoofer","provider":"Big Jeff Online Inc","version":"1.0","type":"link"}
