Hertz MPS 250 S2 10" Mille Pro Subwoofer - Grille Included

Mille PRO shallow subwoofers are designed to obtain peak performance even with limited space to install a subwoofer box.

MPS 300 is optimized to work in ultra-compact sealed boxesstarting from only 22,7 Lt (0.8 Cf). A common example of this is a sub enclosure under the rear bench of a truck where there is little to no space. 

The Mille PRO sub has a never before achieved depth/performance ratio due to the cone excursion capacity that is 20% higher than a normal design. 

The ingenious suspension group design allowed this target to be achieved, it deatures a dedicated support structure for spider and coil. This has allowed the magnetic group to move inwards, minimizing the depth while maximizing cone linear excursion.
