It starts with a double-stacked 8.66″ Y35 ferrite motor on a one-piece bumped T-yoke with a 0.6″ top-plate, a 5mm aluminum magnet-ID shorting ring to level inductance over stroke, and a 0.6″ pole extension to keep the coil controlled at high excursion. The 3″ diameter, 2.36″ long 4-layer aluminum coil is the same unit used in the X v.2 series, giving the U the same 1,500-watt RMS rating. Cooling comes from a high-velocity pole vent, ten back-plate air-gap vents, and cast-aluminum vented frame spacer rings, while a new cast-aluminum frame allows taller, more excursion-capable cones than the Z v.3. Optimized for small ported or bandpass enclosures, the U-Series sounds like the SA series but handles significantly more power.  \u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBlack aluminum 3″ voice coil former for superior heat dissipation\u003c\/li\u003e\n\u003cli\u003eDouble-stacked Y35 ferrite motor with magnet-ID shorting ring and rear pole\/gap venting\u003c\/li\u003e\n\u003cli\u003eHeavy-duty cast aluminum basket with cast-aluminum vented frame spacer ring\u003c\/li\u003e\n\u003cli\u003eDouble-stitched surround and stitched-on double-XL tinsel leads\u003c\/li\u003e\n\u003cli\u003eSpring-loaded terminals accept up to 8 gauge; optimized for small ported or bandpass enclosures\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\u003e1,500W\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″ diameter, 4-layer aluminum, 2.36″ long\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRE (D2 \/ D4)\u003c\/td\u003e\n\u003ctd\u003e3.8 \/ 6.1 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFS (D2 \/ D4)\u003c\/td\u003e\n\u003ctd\u003e42.2 \/ 40.0 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVAS (D2 \/ D4)\u003c\/td\u003e\n\u003ctd\u003e17.9 \/ 12.3 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQts (D2 \/ D4)\u003c\/td\u003e\n\u003ctd\u003e0.27 \/ 0.34\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLe (D2 \/ D4)\u003c\/td\u003e\n\u003ctd\u003e2.41 \/ 3.67 mH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBL (D2 \/ D4)\u003c\/td\u003e\n\u003ctd\u003e31.2 \/ 33.7\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMms (D2 \/ D4)\u003c\/td\u003e\n\u003ctd\u003e290.2 \/ 284.5 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensitivity (D2 \/ D4)\u003c\/td\u003e\n\u003ctd\u003e88.4 dB \/ 85.0 dB @ 1w\/1m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003chr\u003e\u003ch2\u003eSundown Audio UV1 12\" Single Ported Subwoofer Enclosure\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNet Volume\u003c\/strong\u003e - 2.0 cu ft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTuning\u003c\/strong\u003e - 33.0 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Area\u003c\/strong\u003e - 28.89 sq in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSub Cutout\u003c\/strong\u003e - 11.01\"\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 UV1 12\" subwoofer\u003c\/p\u003e\u003cp\u003eThis enclosure is custom built specifically for the Sundown Audio UV1 12\" subwoofer.
