It pairs that frame with a quad-stacked 265mm (10.43″) motor and a 100mm (3.94″) magnet stack — the largest motor ever used on a Z series sub — driving a 3.3″ 4-layer round-wire aluminum voice coil with a 95mm winding length. A patent-pending airflow-directing pole cap, six pole-OD channels, sixteen gap vents, and a cross-drilled top plate keep the coil cool, while a 9mm magnet-ID Faraday ring and pole-extension inductance sleeve deliver highly linear inductance. The result is 42mm of one-way linear excursion by 70% BL with an extremely uniform curve, designed for the lowest bass extension possible in a small ported enclosure with very low distortion.  \u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePatented Sundown “mega-platform” custom-tooled frame\u003c\/li\u003e\n\u003cli\u003eQuad-stacked 265mm (10.43″) motor with 100mm (3.94″) magnet stack\u003c\/li\u003e\n\u003cli\u003e3.3″ 4-layer round-wire aluminum voice coil, 95mm winding length\u003c\/li\u003e\n\u003cli\u003ePatent-pending pole cap, six pole-OD channels, sixteen gap vents, cross-drilled top plate\u003c\/li\u003e\n\u003cli\u003e9mm magnet-ID Faraday ring with pole-extension inductance sleeve\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:35%;\"\u003eImpedance\u003c\/td\u003e\n\u003ctd\u003eDual 1-ohm or Dual 2-ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoice Coil\u003c\/td\u003e\n\u003ctd\u003e3.3″ diameter, 4-layer round-wire aluminum, 95mm winding\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor\u003c\/td\u003e\n\u003ctd\u003eQuad-stacked 265mm (10.43″)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMagnet Stack Height\u003c\/td\u003e\n\u003ctd\u003e100mm (3.94″)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLinear Excursion\u003c\/td\u003e\n\u003ctd\u003e42mm one-way by 70% BL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFaraday Ring\u003c\/td\u003e\n\u003ctd\u003e9mm magnet-ID\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003chr\u003e\u003ch2\u003eSundown Audio ZV7 MDF 18\" Single Ported Subwoofer Enclosure\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNet Volume\u003c\/strong\u003e - 7.0 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 - 101.25 sq in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSub Cutout\u003c\/strong\u003e - 16.69\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e - Dense, uniform, void-free triple refined MDF panel\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 ZV7 MDF 18\" subwoofer\u003c\/p\u003e\u003cp\u003eThis enclosure is custom built specifically for the Sundown Audio ZV7 MDF 18\" subwoofer.
