Music fans who attend live concerts know well the emotions that low undistorted frequencies without dynamic compression can arouse.


For this reason, the Hertz R&D team created Mille car audio subwoofers.

Since its introduction in 1999, the Mille series has always had one goal: to be a reference for the enthusiasts. The Hertz designers’ commitment has been rewarded by both the International press representatives’ and the in-car listening enthusiasts, not to forget the

several awards collected during the time.


The Hertz Design team approaches each new project as a continuous challenge: driven by their passion for music reproduced in car, they constantly improved the performance level compared to the past. To make the difference in your car audio system today.

Huge amounts of resources have been employed in the FEA (Finite Element Analysis) simulations which, through a long phase of material characterization, led to the optimization of each cubic millimetre of the speaker, giving the advantage of predicting performance and sound behaviours in their final application: the car environment!


All of the results of this research course, focused on the cone geometry and their modal analysis, on the surround and spider optimization, on the thermal and magnetic advanced

modeling techniques, allowed to achieve an ambitious goal: to improve the Mille line, a reference product for the enthusiasts.
