Hertz, MPS 300 S4
MPS 300 S4300 (12) mm (in.) | 88 (3.46) mm (in.) | Subwoofers | 1000 W | 4 Ohm | Single Voice Coil
MPS 300 S4 shallow subwoofer has been designed to achieve exceptional performance even when there is very little space available to install the subwoofer box.
MPS 300 is optimized to work in ultra-compact sealed boxesstarting from only 22,7 Lt (0.8 Cf). A typical example is a subwoofer enclosure under the rear bench of pickup trucks, where the space - and the height - are limited.
Mille PRO subwoofer has a depth/performance ratio never achieved before thanks to the impressive cone excursion capacity which is 20% higher than a traditional design.
This exceptional target has been achieved thanks to the ingenious suspension group design featuring a dedicated support structure for the spider and coil. This solution has allowed the movement of the magnetic group inwards, reducing the depth and at the same time maximizing cone linear excursion.
