Sundown balanced the moving mass, motor force, and suspension stiffness for the intended power level, and added a large magnet shorting (faraday) ring to reduce distortion and smooth response across the acoustic spectrum. The coil mates to a robust multi-layer spider with fully tied-on, doubled-up XL tinsel leads, while a competition-grade paper cone, foam surround, and cast aluminum frame complete the build. With ~19mm of one-way linear excursion and a 37mm x-mech limit before coil bottom, it is nearly bottomless at 1250W RMS (2500W peak). \u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAluminum 2.75\" voice coil former for superior heat dissipation\u003c\/li\u003e\n\u003cli\u003eMagnet ID faraday ring for smooth acoustic response\u003c\/li\u003e\n\u003cli\u003eHigh-velocity cast aluminum vented frame spacer ring\u003c\/li\u003e\n\u003cli\u003eHigh-temperature copper voice coil wire with spring-loaded terminals\u003c\/li\u003e\n\u003cli\u003eStitched-on double XL tinsel leads\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\u003e1250 Watts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePeak Power\u003c\/td\u003e\n\u003ctd\u003e2500 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\u003e2.75\" aluminum former\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLinear Excursion\u003c\/td\u003e\n\u003ctd\u003e~19mm one-way\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMechanical Limit\u003c\/td\u003e\n\u003ctd\u003e37mm one-way before coil bottom\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\u003c\/table\u003e\u003chr\u003e\u003ch2\u003eSundown Audio SAV2 12\" Dual Ported Subwoofer Enclosure\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNet Volume\u003c\/strong\u003e - 3.5 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 - 50.62 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 SAV2 12\" subwoofer\u003c\/p\u003e\u003cp\u003eThis enclosure is custom built specifically for the Sundown Audio SAV2 12\" subwoofer.
