For a sub that is so praised, you would think that Rockford Fosgate produced something super special that was like nothing that was available prior to its release, right? No, the whole point about this awesome subwoofer is that you get the most average (read most practical) design that was simply built well. It’s a 12-inch standard round sub that packs a heavy punch on a budget.

The power rating for this model is 600 Watts RMS with peak power set at nearly 1200 Watts. It’s a dual voice coil design that operates at 4 Ohms, which makes it compatible with just about any monoblock out there. Now that we got some raw specs out of the way, let’s address the overall build quality of P3D4. Starting from the cone, we see a solid anodized aluminum piece that is light but and pretty agile. The dust cap is also made of the same material. One of the more unique features is the vertically mounted surround, which in theory increases the efficiency of the cone by some 25%.

Basket features what Rockford Fosgate calls a ‘FlexFit’ design. In simple words, this translates to having slots instead of simple holes for mounting the sub. The benefit of this system is that you can adjust the angle of the sub once you mount it. However, seeing how this design introduces a lateral axis, there might be some issues with the screws coming loose and the whole speaker moving a bit.

Tinsel leads are pretty standard in terms of shape, but they are stitched. Rockford Fosgate decided to hard-stitch the lead wires at certain places along their length, thus achieving a decent combination of flexibility, reliability, and weight.

In terms of heat dissipation, the basket takes care of most of the needs due to its semi-vented design which allows the spider to breathe and release heat away from the magnets. Aside from these features that we have mentioned above, you can also count on seeing a number of cosmetic details such as the PVC magnet cover and a diamond cut, cast aluminum trim ring.

With all that said, the speaker not only feels solid, it also looks pretty attractive. You generally don’t expect the get much eye candy in this price range, but Rockford Fosgate made sure that P3 at least looks decent enough for styling oriented builds.
