Hertz MPS 300 S2

MPS 300 S2 shallow subwoofer has been designed to achieve exceptional performance even when there is very little space available to install the subwoofer box. MPS 300 S2 is optimized to work in ultra-compact sealed boxes starting 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. This exceptional target has been achieved thanks to the ingenious suspension group design featuring a dedicated support structure for spider and coil. This solution has allowed to move the magnetic group inwards, reducing the depth and at the same time maximizing cone linear excursion.

Great product when its on discount

I enjoy these, since this is the first time I had bought this brand and went in blind. The sound sounds great with dual subwoofers. I was able to tell the difference with hearing them in a sealed and sealed/ported boxes. With the sealed/ported they blew me away, the only reason why I didn't go with this route was space on my back trunk, other wise I would be going with ported subwoofers for my go-to. I recommend these.
