{"product_id":"hertz-mp-300-d4-3-pro","title":"HERTZ MP 300 D4.3 PRO","description":"\u003cp\u003e\u003cstrong\u003eOutstanding performance in a compact size\u003c\/strong\u003e, this is the target of Mille Pro car audio subwoofers. On the strength of its \u003cstrong\u003eknow-how acquired with Mille Legend\u003c\/strong\u003e, the R\u0026amp;D team has optimized the production process to offer the “Hertz Sound Experience” to a wider audience using part of the technologies and materials of the flagship line.  The \u003cstrong\u003eMP 300 D4.3\u003c\/strong\u003e cone is made by pressing paper pulp with the injection of mineral powders, the same construction technique used for Legend. The \u003cstrong\u003eV-cone®\u003c\/strong\u003e profile increases rigidity, allowing the cone to function like a piston. Surround materials consist of high-purity \u003cstrong\u003eIIR-butyl rubber\u003c\/strong\u003e. Like the Legend ML2000.3 and ML2500.3, the Mille PRO subwoofers are built with Boundary Free Surround technology allowing for a greater emission surface with equal diameter, generating higher sound pressure. The compact \u003cstrong\u003e6-spoke aluminum alloy anti-resonant\u003c\/strong\u003e basket is the same as the top model ML 2500.3 and contributes to the subwoofer’s mechanical damping, being absolutely transparent to the sound.  The\u003cstrong\u003e 65-mm 4-layer voice coil\u003c\/strong\u003e \u003cstrong\u003eis higher than 60 mm\u003c\/strong\u003e and wound in a TIL-P former, thus delivering high linear displacement. The\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e4 Ω + 4 Ω DVC impedance configuration improves versatility\u003c\/strong\u003e to match any amplifier system. The air cooling and decompression system avoids the need for a centre hole on the bottom plate with three advantages:\u003c\/p\u003e\n\u003cp\u003e- \u003cstrong\u003eBetter thermal inertia\u003c\/strong\u003e to ensure low operating temperatures during musical transients;\u003cbr\u003e- \u003cstrong\u003eMaximization of the magnetic field induced\u003c\/strong\u003e to the coil with the same overall motor dimensions. Thanks to a greater amount of iron in the pole the likelihood of magnetic saturation decreases exploiting the maximum flux density generated from the magnet;\u003cbr\u003e- Possibility to \u003cstrong\u003einstall the subwoofer right on the box wall\u003c\/strong\u003e, taking full advantage of its minimal dimensions. A damping rubber disk, provided with the product, secures the subwoofer to the box and ensures air exchange for the 10 vents on the bottom.\u003c\/p\u003e\n\u003cp\u003eThe holes behind the voice coil winding and \u003cstrong\u003ethe 10 vents on the bottom plate ensure greater air exchange\u003c\/strong\u003e to the coil inner layers and work in synergy with an innovative assembly system. It forces the air to pass through the air gap to keep the coil operating temperature low, even with the most extreme musical programs. The terminal uses \u003cstrong\u003esolid push connectors with an antishort circuit cover\u003c\/strong\u003e accepting cables up to 8 AWG to provide ultra-low wiring resistance in low impedance configurations (1ohm).\u003c\/p\u003e\n\u003cdiv class=\"pp_layer clearfix\"\u003e\n\u003cdiv class=\"prod_half flright\"\u003e\n\u003ch4 class=\"ph_titile\"\u003eData table\u003c\/h4\u003e\n\u003ctable class=\"data_table\"\u003e\n\u003ctbody\u003e\n\u003ctr class=\"tr_colored\"\u003e\n\u003ctd\u003e\n\u003cb\u003eSize\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003emm (in.)\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e300 (12)\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cb\u003ePower Handling - Peak\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003eW\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e1200\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"tr_colored\"\u003e\n\u003ctd\u003e\n\u003cb\u003ePower Handling - Continuous\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003eW\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e600\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cb\u003eImpedance\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003eΩ\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e4+4\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"tr_colored\"\u003e\n\u003ctd\u003e\n\u003cb\u003eSensitivity\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003edB SPL\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e86\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cb\u003eVoice coil Ø\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003emm (in.)\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e65 (2,5)\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"tr_colored\"\u003e\n\u003ctd\u003e\n\u003cb\u003eXmax\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003emm\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e17\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cb\u003eX-mech\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003emm (in.)\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e±27 (1.06)\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"tr_colored\"\u003e\n\u003ctd\u003e\n\u003cb\u003eRe\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003eΩ\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e1,9 (coils in PARALLEL)\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cb\u003eFs\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003eHz\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e24\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"tr_colored\"\u003e\n\u003ctd\u003e\n\u003cb\u003eVas\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003el\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e74\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eQts\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e0,42\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"tr_colored\"\u003e\n\u003ctd\u003e\u003cb\u003eQes\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e0,45\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eQms\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e5,9\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"tr_colored\"\u003e\n\u003ctd\u003e\n\u003cb\u003eSpl\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003edB\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e86\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp_layer clearfix\"\u003e\n\u003cdiv class=\"prod_half flleft\"\u003e\n\u003ch4 class=\"ph_titile\"\u003eFeatures\u003c\/h4\u003e\n\u003ca class=\"fancybox\" href=\"http:\/\/www.hertzaudiovideo.com\/wp-content\/uploads\/2016\/07\/Hertz_Mille_PRO_MP300_D4_section.png\"\u003e\u003cimg alt=\"\" src=\"http:\/\/www.hertzaudiovideo.com\/wp-content\/uploads\/2016\/07\/Hertz_Mille_PRO_MP300_D4_section.png\"\u003e\u003c\/a\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"prod_half flright\"\u003e\n\u003cdiv class=\"padd-40\"\u003e\n\u003cp\u003e1.
