Kicker CompR vs Rockford Fosgate P3 Subwoofer
The Kicker CompR subwoofers offer hard-hitting bass that is accurate and designed for sound quality. The Kicker CompR subwoofers are an updated version of the legendary CompVR. The CompR features a ribbed polypropylene surround and the cone does not feature the raised spokes that the CompVR has. As a result, there is less distortion from the CompR when it is hitting hard at loud volume and it does not have the "knock" that the CompVR has. If you are looking for hard-hitting, accurate bass, the Kicker CompR subwoofer is a great choice.
Rockford Fosgate P3
Rockford Fosgate designed the P3 subwoofers to stay strong even when the bass gets hot. This Punch P3 sub features a rigid anodized aluminum cone that holds its shape through heavy play while staying light and responsive. Rockford Fosgate uses a new technique to attach the oversized rubber surround to the cone that increases the available cone area up to 25%, so this sub can push more air for even bigger bass. The aluminum cone acts as a giant heat sink, directing heat away from the copper-clad aluminum voice coils. Special venting keeps the voice coils cool, so you get incredibly consistent bass performance over time. These P3 subs feature an extended pole piece and bumped backplate that leaves more room for a heavy excursion, so it'll hit deeper lows without "bottoming out." The dual 4-ohm voice coils allow you to wire the sub for 2-ohm impedance to get maximum power output, or for 8-ohm impedance if you're using multiple subs. The P3 series subs work equally well in a sealed or ported enclosure, so you can choose the kind of bass you want for your system.
