Description

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

The MPS 300 S4 (12-inch) is optimized to work in ultra-compact sealed enclosures starting from just 22.7 liters (0.8 Cf). A typical example is a subwoofer enclosure under the rear seats of pickup trucks, where space – and height – are limited.

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

This exceptional objective was achieved through the ingenious design of the suspension system, featuring a dedicated support structure for the spider and voice coil. This solution allowed the magnet assembly to be moved inward, reducing depth while maximizing linear cone excursion.
