The MILLE PRO MPS 250 S4/S2, manufactured by renowned audio manufacturer Hertz, is a 10" (25cm) subwoofer known for its impressive performance despite its flat design. This subwoofer is optimized for use in ultra-compact, closed cabinets and offers exceptional performance despite limited space. Its special design allows it to achieve high performance even in difficult installation conditions, such as under the back seat of pickup trucks. With a cone excursion capacity that is 20% higher than conventional designs, this subwoofer offers a bass/power ratio that is second to none.

MPS 250 S4
The low-profile MPS 250 S4 subwoofer has been designed to deliver exceptional performance even when there is very little space available for installing the subwoofer enclosure.
The MPS 250 S2 is optimized for use in ultra-compact, closed enclosures from 14 Lt (0.49 Cf). A typical example is a subwoofer enclosure under the back seat of pickups where space and height are limited.
The MPS 250 subwoofer has an unprecedented bass-to-power ratio thanks to its impressive cone excursion capacity, which is 20% higher than a conventional design.
This extraordinary goal was achieved thanks to the ingenious design of the centering with a special support structure for the spider and coil. This solution has made it possible to move the magnet inwards, reducing the depth while maximizing the linear excursion of the diaphragm.
