The key is its FEA-optimized spider and surround, paired with the custom-tooled 8″ frame that represents the maximum performance possible on that platform. The motor and coil deliver roughly 19mm of one-way linear Xmax — about 2.4″ peak-to-peak before the coil leaves the gap — and an aluminum magnet-ID shorting ring reduces inductive distortion. The 800-watt RMS rating is quite conservative. Available in D2 and D4, it’s right at home in small sealed or ported enclosures.  \u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFEA-optimized spider and surround for low distortion\u003c\/li\u003e\n\u003cli\u003eCustom-tooled 8″ frame platform maxed for output\u003c\/li\u003e\n\u003cli\u003e~19mm one-way linear Xmax (~2.4″ p-p before the coil leaves the gap)\u003c\/li\u003e\n\u003cli\u003eAluminum magnet-ID shorting ring for reduced inductive distortion\u003c\/li\u003e\n\u003cli\u003eConservative 800-watt RMS rating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eRMS Power\u003c\/td\u003e\n\u003ctd\u003e800W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImpedance\u003c\/td\u003e\n\u003ctd\u003eDual 2-ohm or Dual 4-ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eXmax\u003c\/td\u003e\n\u003ctd\u003e19mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRE (D2 \/ D4)\u003c\/td\u003e\n\u003ctd\u003e4.0 \/ 6.0 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFS (D2 \/ D4)\u003c\/td\u003e\n\u003ctd\u003e47.4 \/ 49.6 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVAS (D2 \/ D4)\u003c\/td\u003e\n\u003ctd\u003e3.6 \/ 3.2 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQts (D2 \/ D4)\u003c\/td\u003e\n\u003ctd\u003e0.31 \/ 0.36\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBL (D2 \/ D4)\u003c\/td\u003e\n\u003ctd\u003e26.0 \/ 30.7\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensitivity (D2 \/ D4)\u003c\/td\u003e\n\u003ctd\u003e82.1 \/ 81.8 dB @ 1w\/1m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSealed Enclosure\u003c\/td\u003e\n\u003ctd\u003e0.3 – 0.4 cu ft\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePorted Enclosure\u003c\/td\u003e\n\u003ctd\u003e0.75 – 1.0 cu ft\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Tuning\u003c\/td\u003e\n\u003ctd\u003e32Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Port Area\u003c\/td\u003e\n\u003ctd\u003e12 – 16 sq in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplacement\u003c\/td\u003e\n\u003ctd\u003e0.13 cu ft\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Depth\u003c\/td\u003e\n\u003ctd\u003e6.8″\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutside Diameter\u003c\/td\u003e\n\u003ctd\u003e8.70″\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCut-Out\u003c\/td\u003e\n\u003ctd\u003e7.36″\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003chr\u003e\u003ch2\u003eSundown Audio XV3 8\" Single Ported Subwoofer Enclosure\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNet Volume\u003c\/strong\u003e - 1.0 cu ft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTuning\u003c\/strong\u003e - 34.0 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Area\u003c\/strong\u003e - 14.5 sq in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSub Cutout\u003c\/strong\u003e - 7.375\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e - 3\/4\" (18mm) birch plywood construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eThis Listing Includes:\u003c\/strong\u003e (1) Basshead Supply ported enclosure for the Sundown Audio XV3 8\" subwoofer\u003c\/p\u003e\u003cp\u003eThis enclosure is custom built specifically for the Sundown Audio XV3 8\" subwoofer.
