Made for competitors and serious bass lovers, it pairs DD's largest ferrite motor with the aluminum Dual Stage Heat Sink, USA-made Iron Cloth Spider System, and 2nd Gen V-ROM surround. It handles 3200W RMS with bursts up to 9600W peak. The handcrafted, carbon fiber-loaded pulp cone is built to last and stay clean under pressure, while the Free Flow Cooling System helps protect the voice coil from overheating. This sub is optimized for large ported enclosures.\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 that big 15\" cone and cleaner, more controlled bass across the whole power range. Power handling stays the same as the standard 9915C, 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: 15 inches\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eRMS Watts: 3200 (same as standard model)\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003ePeak Watts: 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: 14.25 inches\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eResonant Frequency (Fs): 34.32 Hz\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eQms: 6.551\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eQes: 0.426 (standard model)\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eQts: 0.400 (standard model)\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eVas: 54.38 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\u003c\/ul\u003e\u003cbr\u003e\n\u003cp\u003e\u003cem\u003eSuggested Enclosure Specifications\u003c\/em\u003e\u003c\/p\u003e\u003cbr\u003e\n\u003cul\u003e\n\u003cbr\u003e\n  \u003cli\u003eWoofer Displacement: 0.4 cu. ft.\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eRecommended Ported Enclosure: 3.0 - 6.0 cu. ft.\u003c\/li\u003e\n\u003cbr\u003e\n\u003c\/ul\u003e\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\n\u003cul\u003e\n\u003cbr\u003e\n  \u003cli\u003eFrame Outer Diameter (OD): 16.62 inches\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eFrame OD with Gasket: 16.75 inches\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eMounting Diameter: 15.19 inches\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eMounting Depth: 10.31 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\u003eShipping Weight: 87 lbs\u003c\/li\u003e\n\u003cbr\u003e\n\u003c\/ul\u003e\u003cbr\u003e\n\u003cp\u003eIf you want the biggest 9900 motor driving a 15\" with even more control, the SuperCharged 9915C is the one to grab.\u003c\/p\u003e","brand":"DD Audio","offers":[{"title":"Default Title","offer_id":67972053532920,"sku":"DD-9915C-D1-SC","price":1029.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0029\/9384\/8365\/files\/825134325610ff9d191a775ee8b24b2dc1ff8264cafc9fd1172d3847f1b286f1_0746ec28-b018-4647-81c3-560b54ef0725.jpg?v=1793804183","url":"https:\/\/bigjeffaudio.com\/products\/dd-audio-9915c-d1-supercharged-15-3200w-rms-dual-1-ohm-usa-built-subwoofer","provider":"Big Jeff Online Inc","version":"1.0","type":"link"}
