Mille PRO shallow subwoofers have been designed to achieve exceptional performance even when there is very little space available to install the subwoofer box.

MPS 250 S4 is optimized to work in ultra-compact sealed boxesstarting from only 14 Lt (0.49 Cf). A typical example is a subwoofer enclosure under the rear bench of pickup trucks, where the space - and the height - are limited.

Mille PRO subwoofer have a depth/performance ratio never achieved before thanks to the impressive cone excursion capacity which is 20% higher than a traditional design.

This exceptional target has been achieved thanks to the ingenious suspension group design featuring a dedicated support structure for spider and coil. This solution has allowed to move the magnetic group inwards, reducing the depth and at the same time maximizing cone linear excursion.

eID (Elettromedia Identification)

The exclusive technology providing the traceability of the Mille.3 products from their birth on. Once the test phase has been passed, the code linked to destination country/market is applied. When purchasing the product, by scanning the code, the user can check through the web the information about the product and can log into the registration page.

Air Innovative Route

Hertz R&D has developed the proprietary AIR (Air Intercooling Revolution) technology, optimizing the fluid dynamics inside the voice coil inner chamber and the magnetic group to minimize the internal compression of air and maximize cooling capacity.

Grille

Provided with MPS 250 there is a full metal sturdy structure composed by a solid cast aluminium ring and a steel mesh black grille featuring an elegant diamond-cut Hertz Logo Mounting screws totally hidden for a superior integration within the car cabin.
