Hertz MP 250 D4.3 - SUBWOOFER 250mm 4+4 Ohm





Outstanding performance in a compact size, this is the target of Mille Pro car audio subwoofers. On the strength of its know-how acquired with Mille Legend, 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 MP 250 D4.3 cone is made by pressing paper pulp with the injection of mineral powders, the same construction technique used for Legend. The V-cone® profile increases rigidity, allowing the cone to function like a piston. Surround materials consist of high-purity IIR-butyl rubber. 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.
