Rated at 3,500 watts RMS and 7,000 watts maximum power, the CARBON18.1D combines exceptional power handling with a high-excursion design to move massive amounts of air and produce deep, powerful bass. Its dual 1-ohm voice coil configuration provides flexible wiring options, allowing installers to configure the subwoofer for different amplifier loads.\u003c\/p\u003e \u003cp\u003eThe CARBON18.1D combines premium materials with a powerful motor structure designed to handle extreme power while maintaining reliable performance. Its carbon-fiber cone and carbon-fiber dust cap provide a lightweight and rigid diaphragm designed for controlled movement and responsive bass reproduction. A 3.5\" aluminum voice coil with CCAR winding supports high power handling and improved heat dissipation during extended high-power operation, while the massive 425 oz ferrite magnet provides the motor force needed for high-excursion performance. The foam surround and aluminum basket support the moving assembly during demanding use, while 22.5 mm of one-way Xmax allows the 18-inch driver to achieve substantial cone travel and air displacement. With a 10–200 Hz frequency response, the CARBON18.1D is built for serious high-output systems where deep, powerful bass is the priority.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eHigh-Power 18\" Subwoofer – Delivers 3,500W RMS and 7,000W maximum power handling for extreme bass performance\u003c\/li\u003e \u003cli\u003eDual 1-Ohm Voice Coils – Provides flexible wiring configurations for high-powered amplifier systems\u003c\/li\u003e \u003cli\u003eCarbon-Fiber Cone – Provides a lightweight and rigid diaphragm for powerful, controlled bass reproduction\u003c\/li\u003e \u003cli\u003eCarbon-Fiber Dust Cap – Reinforces the cone assembly while supporting the subwoofer's high-performance construction\u003c\/li\u003e \u003cli\u003eHigh-Excursion Design – Features 22.5 mm of one-way Xmax for increased cone movement and substantial air displacement\u003c\/li\u003e \u003cli\u003e3.5\" Aluminum Voice Coil – Designed for high power handling and improved heat dissipation\u003c\/li\u003e \u003cli\u003eCCAR Voice Coil Winding – Supports reliable performance under demanding high-power conditions\u003c\/li\u003e \u003cli\u003e425 oz Ferrite Magnet – Delivers substantial motor force for high-output bass applications\u003c\/li\u003e \u003cli\u003eFoam Surround – Supports controlled high-excursion cone movement while providing durability\u003c\/li\u003e \u003cli\u003e9\" Spider – Supports the moving assembly during high-excursion operation\u003c\/li\u003e \u003cli\u003eAluminum Basket – Provides a strong and rigid foundation for the motor and moving components\u003c\/li\u003e \u003cli\u003e4-Gauge Push Terminals – Accommodates heavy-gauge speaker wire for high-powered installations\u003c\/li\u003e \u003cli\u003eImproved Heat Management – Designed to help manage heat during extended high-power operation\u003c\/li\u003e \u003cli\u003eSPL-Oriented Design – Engineered for high-output systems and serious competition-oriented bass applications\u003c\/li\u003e \u003cli\u003eSealed and Ported Enclosure Compatible – Designed for properly sized sealed or ported enclosure applications\u003c\/li\u003e \u003cli\u003eCARBON Series Performance – Built for high-powered car audio systems where deep, powerful bass is the priority\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eModel: CARBON18.1D\u003c\/li\u003e \u003cli\u003eSeries: CARBON\u003c\/li\u003e \u003cli\u003eSubwoofer Size: 18\"\u003c\/li\u003e \u003cli\u003eVoice Coil Configuration: Dual 1-Ohm\u003c\/li\u003e \u003cli\u003eNominal Impedance: 1 + 1 Ohms\u003c\/li\u003e \u003cli\u003ePower Handling RMS: 3,500 Watts\u003c\/li\u003e \u003cli\u003ePower Handling MAX: 7,000 Watts\u003c\/li\u003e \u003cli\u003eSensitivity: 85 dB\u003c\/li\u003e \u003cli\u003eFrequency Response: 10–200 Hz\u003c\/li\u003e \u003cli\u003eRecommended Low-Pass Crossover: 60 Hz\u003c\/li\u003e \u003cli\u003eCone Shape: Conic\u003c\/li\u003e \u003cli\u003eCone Material: Carbon Fiber\u003c\/li\u003e \u003cli\u003eDustcap Material: Carbon Fiber\u003c\/li\u003e \u003cli\u003eDustcap Size: 8\" (200 mm)\u003c\/li\u003e \u003cli\u003eSurround Material: Foam\u003c\/li\u003e \u003cli\u003eVoice Coil Diameter: 3.5\" (89 mm)\u003c\/li\u003e \u003cli\u003eVoice Coil Former Material: Aluminum\u003c\/li\u003e \u003cli\u003eVoice Coil Winding: CCAR\u003c\/li\u003e \u003cli\u003eSpider Diameter: 9\" (228 mm)\u003c\/li\u003e \u003cli\u003eLeads Connection Type: Spider Crossed\u003c\/li\u003e \u003cli\u003eBasket Material: Aluminum\u003c\/li\u003e \u003cli\u003eBasket Finish: Aluminum \/ Black\u003c\/li\u003e \u003cli\u003eMagnet Material: Ferrite\u003c\/li\u003e \u003cli\u003eMagnet Weight: 425 oz\u003c\/li\u003e \u003cli\u003eSpeaker Terminals: 4-Gauge Push Terminals\u003c\/li\u003e \u003cli\u003eXmax: 22.5 mm One-Way\u003c\/li\u003e \u003cli\u003eOverall Diameter: 18.5\" (470 mm)\u003c\/li\u003e \u003cli\u003eOverall Depth: 14\" (355 mm)\u003c\/li\u003e \u003cli\u003eMounting Depth: 12.15\" (309 mm)\u003c\/li\u003e \u003cli\u003eFront Mount Baffle Cutout: 16.75\" (426 mm)\u003c\/li\u003e \u003cli\u003eMotor Diameter: 9\" (230 mm)\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003ePackage Includes\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e1 × DS18 CARBON18.1D 18\" Dual 1-Ohm High Excursion Subwoofer\u003c\/li\u003e \u003cli\u003e1 × Owner's Manual\u003c\/li\u003e \u003cli\u003eMounting Hardware\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eSKU: DS-CARBON18.1D\u003cbr\u003eUPC: 810199442419\u003c\/p\u003e\u003ch3\u003eWhy buy from Stereo-Needs\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFree shipping on every order\u003c\/li\u003e\n\u003cli\u003eFamily business with 20+ years selling car audio and 429,000+ items sold on eBay (99.9% positive)\u003c\/li\u003e\n\u003cli\u003eNot sure it fits your vehicle or system?
