On the strength of its <strong>know-how acquired with Mille Legend</strong>, the R&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 <strong>MP 250 D2.3</strong> cone is made by pressing paper pulp with the injection of mineral powders, the same construction technique used for Legend. The <strong>V-cone®</strong> profile increases rigidity, allowing the cone to function like a piston. Surround materials consist of high-purity <strong>IIR-butyl rubber</strong>. 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 <strong>6-spoke aluminum alloy anti-resonant</strong> 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<strong> 65-mm 4-layer voice coil</strong><strong>is higher than 60 mm</strong> and wound in a TIL-P former, thus delivering high linear displacement. The <strong>2 Ω 2 Ω DVC impedance configuration improves versatility</strong> 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:</p> <p>– <strong>Better thermal inertia</strong> to ensure low operating temperatures during musical transients;<br /> – <strong>Maximization of the magnetic field induced</strong> 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;<br /> – Possibility to <strong>install the subwoofer right on the box wall</strong>, 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.</p> <p>The holes behind the voice coil winding and <strong>the 10 vents on the bottom plate ensure greater air exchange</strong> 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 <strong>solid push connectors with an antishort circuit cover</strong> accepting cables up to 8 AWG to provide ultra-low wiring resistance in low impedance configurations (1ohm).</p> </div> </div> <h4><span style="color: #ff6600;">Technical Specs</span></h4> <table class="table caption-top"> <tbody> <tr> <td><strong>Size</strong> mm (in.)</td> <td>250 (10)</td> </tr> <tr> <td><strong>Power Handling – Continuous</strong> W</td> <td>600</td> </tr> <tr> <td><strong>Power Handling – Peak</strong> W</td> <td>1200</td> </tr> <tr> <td><strong>Impedance</strong> Ohm</td> <td>2 2</td> </tr> <tr> <td><strong>No Filter Component</strong></td> <td>Subwoofers</td> </tr> <tr> <td><strong>Voice Coil Ø</strong></td> <td>65 (2.56)</td> </tr> <tr> <td><strong>Magnet size D x d x h</strong> mm (in.)</td> <td>165 x 75 x 35 (6.5 x 2.95 x 1.38)</td> </tr> <tr> <td><strong>Weight of one component</strong> kg (lb.)</td> <td>8,2 (18.08)</td> </tr> <tr> <td><strong>Magnet</strong></td> <td>High density flux ferrite</td> </tr> <tr> <td><strong>Cone</strong></td> <td>Pressed-pulp cone with mineral powders</td> </tr> <tr> <td><strong>Xmech</strong> mm (in.)</td> <td>±27 (1.06)</td> </tr> </tbody> </table> <h4><span style="color: #ff6600;">Electro-acoustic Specs</span></h4> <table class="table caption-top table--m--ww"> <tbody> <tr> <td><strong>D</strong> mm</td> <td>213</td> </tr> <tr> <td><strong>Xmax</strong> mm</td> <td>17,00</td> </tr> <tr> <td><strong>Re</strong> Ohm</td> <td>0,85</td> </tr> <tr> <td><strong>Fs</strong> Hz</td> <td>30,00</td> </tr> <tr> <td><strong>Le</strong> mH</td> <td>0б65</td> </tr> <tr> <td><strong>Vas</strong> I</td> <td>25,00</td> </tr> <tr> <td><strong>Mms</strong> g</td> <td>182,00</td> </tr> <tr> <td><strong>Cms</strong> mm/N</td> <td>0,14</td> </tr> <tr> <td><strong>BL</strong> T*m</td> <td>7,1</td> </tr> <tr> <td><strong>Qts</strong></td> <td>0,54</td> </tr> <tr> <td><strong>Qes</strong></td> <td>0,6</td> </tr> <tr> <td><strong>Qms</strong></td> <td>5,92</td> </tr> <tr> <td><strong>Spl</strong> dB</td> <td>83,5</td> </tr> </tbody> </table> <h4><span style="color: #ff6600;">Physical Specs</span></h4> <div class="table-responsive-sm"> <p><a class="float-start mb-3" href="https://static.hertz-audio.com/media/2021/07/HERTZ_Mille-PRO_MP250_3_D2_Tech_Sheet_size.png" data-fancybox="product-physical-specs"><img loading="lazy" decoding="async" class="attachment-full size-full" src="https://static.hertz-audio.com/media/2021/07/HERTZ_Mille-PRO_MP250_3_D2_Tech_Sheet_size.png" sizes="auto, (max-width: 800px) 100vw, 800px" srcset="https://static.hertz-audio.com/media/2021/07/HERTZ_Mille-PRO_MP250_3_D2_Tech_Sheet_size.png 800w, https://static.hertz-audio.com/media/2021/07/HERTZ_Mille-PRO_MP250_3_D2_Tech_Sheet_size-300x225.png 300w, https://static.hertz-audio.com/media/2021/07/HERTZ_Mille-PRO_MP250_3_D2_Tech_Sheet_size-768x576.png 768w" alt="MP 250 D2.3 PRO" width="800" height="600" /></a></p> <div class="table-responsive-sm"> <table class="table caption-top"> <tbody> <tr> <td><strong>A</strong></td> <td>268 mm</td> <td>10.55 in.</td> </tr> <tr> <td><strong>B</strong></td> <td>236 mm</td> <td>9.29 in.</td> </tr> <tr> <td><strong>C</strong></td> <td>160 mm</td> <td>6.3 in.</td> </tr> <tr> <td><strong>D</strong></td> <td>141 mm</td> <td>5.55 in.</td> </tr> <tr> <td><strong>E</strong></td> <td>274 mm</td> <td>10.79 in.</td> </tr> <tr> <td><strong>F</strong></td> <td>58,5 mm</td> <td>2.3 in.</td> </tr> </tbody> </table> </div> </div> <h4><span style="color: #ff6600;">Features</span></h4> <p>1.
