Description

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

The MPS 250 S4 is optimized to work in ultra-compact sealed enclosures starting from just 14 liters (0.49 Cf). A typical example is a subwoofer enclosure under the rear seat of pickup trucks, where space - and height - are limited.

The Mille PRO subwoofer has an unprecedented depth-to-performance ratio thanks to the impressive cone excursion capability, which is 20% greater than a traditional design.

This exceptional goal was achieved thanks to the ingenious design of the suspension system, featuring a dedicated support structure for the spider and voice coil. This solution allowed the magnetic assembly to be shifted inward, reducing depth and at the same time maximizing the linear excursion of the cone.
