Engineered specifically for bassheads, SPL enthusiasts, and high-power custom enclosure builds, the Storm 12 D4 combines a heavy-duty voice coil, high-flux ferrite motor assembly, and a reinforced cone structure to handle demanding bass notes without thermal compression or mechanical failure. Featuring dual 4-ohm high-temperature voice coils, the Storm 12 D4 offers versatile wiring flexibility (configurable to a 2-ohm parallel or 8-ohm series load for single sub setups, or a 1-ohm load for dual subwoofer setups), making it an ideal match for high-power monoblock Class D amplifiers in ported, slot-ported, or bandpass subwoofer boxes.\u003c\/p\u003e\n\u003ch2 data-path-to-node=\"5\"\u003eKey Features \u0026amp; Performance Highlights\u003c\/h2\u003e\n\u003cul data-path-to-node=\"6\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,0,0\"\u003e\u003cb data-path-to-node=\"6,0,0\" data-index-in-node=\"0\"\u003eHigh-Power Handling Construction:\u003c\/b\u003e Designed with heavy-duty motor geometry and high-temperature voice coil windings to deliver high SPL volume output and deep bass response.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,1,0\"\u003e\u003cb data-path-to-node=\"6,1,0\" data-index-in-node=\"0\"\u003eDual 4-Ohm Voice Coil Configuration:\u003c\/b\u003e Provides ultimate amplifier wiring flexibility, allowing you to wire a single driver to 2 ohms, or run a pair of subs down to a 1-ohm load on high-power monoblock amplifiers.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,2,0\"\u003e\u003cb data-path-to-node=\"6,2,0\" data-index-in-node=\"0\"\u003eReinforced Non-Press Paper Cone:\u003c\/b\u003e Lightweight yet rigid cone structure prevents flex during heavy excursion, ensuring clean, punchy low-frequency impact.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,3,0\"\u003e\u003cb data-path-to-node=\"6,3,0\" data-index-in-node=\"0\"\u003eHigh-Roll Foam Surround:\u003c\/b\u003e Heavy-duty stitched high-roll surround allows linear cone displacement and maximum air movement for deep low-end extension.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,4,0\"\u003e\u003cb data-path-to-node=\"6,4,0\" data-index-in-node=\"0\"\u003eHeavy-Duty Cast Frame Chassis:\u003c\/b\u003e Rigid, anti-resonant basket structure shields the moving motor assembly and provides perimeter cooling vents for maximum heat dissipation.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-path-to-node=\"7\"\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul data-path-to-node=\"8\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,0,0\"\u003e\u003cb data-path-to-node=\"8,0,0\" data-index-in-node=\"0\"\u003eBrand \u0026amp; Series:\u003c\/b\u003e Aura Car Audio (Storm Series)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,1,0\"\u003e\u003cb data-path-to-node=\"8,1,0\" data-index-in-node=\"0\"\u003eModel:\u003c\/b\u003e Storm 12 D4\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,2,0\"\u003e\u003cb data-path-to-node=\"8,2,0\" data-index-in-node=\"0\"\u003eSubwoofer Size:\u003c\/b\u003e 12 Inch (300 mm)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,3,0\"\u003e\u003cb data-path-to-node=\"8,3,0\" data-index-in-node=\"0\"\u003eVoice Coil Configuration:\u003c\/b\u003e Dual 4-Ohm (D4)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,4,0\"\u003e\u003cb data-path-to-node=\"8,4,0\" data-index-in-node=\"0\"\u003eVoice Coil Diameter:\u003c\/b\u003e High-Temperature Aluminum Former\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,5,0\"\u003e\u003cb data-path-to-node=\"8,5,0\" data-index-in-node=\"0\"\u003eCone Material:\u003c\/b\u003e Reinforced Non-Press Paper Cone with High-Roll Surround\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,6,0\"\u003e\u003cb data-path-to-node=\"8,6,0\" data-index-in-node=\"0\"\u003eBasket Material:\u003c\/b\u003e Die-Cast Frame \/ Heavy-Duty Stamp Steel\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,7,0\"\u003e\u003cb data-path-to-node=\"8,7,0\" data-index-in-node=\"0\"\u003eMagnet Assembly:\u003c\/b\u003e High-Grade High-Flux Ferrite Motor\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,8,0\"\u003e\u003cb data-path-to-node=\"8,8,0\" data-index-in-node=\"0\"\u003eImpedance Options:\u003c\/b\u003e 2 Ohms (Parallel Wiring) \/ 8 Ohms (Series Wiring) \/ 1 Ohm (Pair in Parallel)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,9,0\"\u003e\u003cb data-path-to-node=\"8,9,0\" data-index-in-node=\"0\"\u003eOptimal Enclosure Type:\u003c\/b\u003e Custom Ported \/ Slot-Ported Enclosure \u0026amp; Sealed Enclosure\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-path-to-node=\"9\"\u003eFrequently Asked Questions (FAQs)\u003c\/h2\u003e\n\u003ch3 data-path-to-node=\"10\"\u003e1.
