Sound Express is an authorized dealer for Hertz Audio.


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.
