A double-stacked 9.4-inch ferrite magnet system is coupled to a thick top plate, with shorting rings inside the magnets and on the pole cap to smooth frequency response while doubling as a heat sink and airflow guide. The custom cast aluminum frame is substantially thicker with heat-dissipation ribs, and the extended pole piece keeps the coil under perfect control under high stress. Coil temperature is managed with machined high-velocity pole channels and 16 direct air-gap vents in the back plate. Rated at 2000W RMS (4000W peak) with dual 2 or 4 ohm coils. \u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAluminum 3\" voice coil former for superior heat dissipation\u003c\/li\u003e\n\u003cli\u003eDouble-stacked 9.4\" ferrite magnet with shorting rings\u003c\/li\u003e\n\u003cli\u003eSolid pole with vent channels and aluminum shorting ring cap\u003c\/li\u003e\n\u003cli\u003e16 direct air-gap vents and top-plate cooling channels\u003c\/li\u003e\n\u003cli\u003eSpring-loaded terminals accept up to 8-gauge wire\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eRMS Power\u003c\/td\u003e\n\u003ctd\u003e2000 Watts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePeak Power\u003c\/td\u003e\n\u003ctd\u003e4000 Watts\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\u003eVoice Coil\u003c\/td\u003e\n\u003ctd\u003e3\" aluminum former\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMagnet\u003c\/td\u003e\n\u003ctd\u003eDouble-stacked 9.4\" ferrite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrame\u003c\/td\u003e\n\u003ctd\u003eCast aluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Enclosure\u003c\/td\u003e\n\u003ctd\u003eSmall ported or bandpass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003chr\u003e\u003ch2\u003eSundown Audio UV2 18\" Single Ported Subwoofer Enclosure\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNet Volume\u003c\/strong\u003e - 5.75 cu ft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTuning\u003c\/strong\u003e - 30.0 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Area\u003c\/strong\u003e - 83.28 sq in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSub Cutout\u003c\/strong\u003e - 16.9\"\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 UV2 18\" subwoofer\u003c\/p\u003e\u003cp\u003eThis enclosure is custom built specifically for the Sundown Audio UV2 18\" subwoofer.
