Hertz Mille Pro MPS 250 S4 / S2

Beschreibung

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 slim design. Optimized for use in ultra-compact, sealed enclosures, this subwoofer delivers 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 diaphragm excursion capacity that is 20% higher than conventional designs, this subwoofer offers a depth/power ratio that is unparalleled.

MPS 250 S4

The MPS 250 S4 flat subwoofer has been designed to deliver exceptional performance even when there is very little space available to install the subwoofer enclosure.


The MPS 250 S2 is optimized for use in ultra-compact, sealed enclosures starting at 14 Lt (0.49 Cf). A typical example is a subwoofer enclosure under the rear seat of pickup trucks, where space and height are limited.


The MPS 250 subwoofer has an unprecedented bass/power ratio thanks to its impressive diaphragm excursion capacity, which is 20% higher than a conventional design.


This exceptional objective 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 membrane.
