Battle of the Subwoofers: Rockford Fosgate P3 vs Kicker L7

Here at Sonic Electronix we are constantly being asked what subwoofer is better. This only becomes a problem when comparing two great subwoofers. At this point the word “better” no longer applies and instead it becomes which one is best for my application? This series will showcase two car subwoofers at a time, drawing out the features that make that particular subwoofer better for one application than the other. This will help you decide which woofer is better for you.

Rockford Fosgate P3D2-12

P3D2-12

First up is the Rockford Fosgate P3D2-12 Punch P3 series subwoofer. This woofer is rated at 600W RMS and features multiple technologies that make a solid and great woofer. Double stacked magnets provide the driving force need for this woofer to really hit hard, while the VAST surround increases the effective radiating cone area increasing nominal efficiency and maximum output. This is what we call the “all around” woofer, great for those who want accurate and loud bass. This woofer will offer clean bass that isn’t too punchy but still provides a nice reproduction of lower frequencies. This type of woofer is perfect for those who listen to music with a faster beat.

Kicker Solo-Baric 11S12L72

11S12L72

Unlike the P3 the Kicker 11S12L72 Solo-Baric L7 subwoofer was made more for SPL than SQ. Rated at 750W RMS, this woofer is able to handle a bit more than the P3, giving you a much louder bass. Its unique square design gives the woofer more surface area which allows for more air movement and thus a louder sounding bass. The L7 also has a lower frequency response which allows it to have a more resonant lower frequency reproduction. This is the kind of woofer you want when listening to music with deep bass, such has Rap and Hip-Hop. That type of music has elongated lower notes that are often missed with other woofers but not with the L7.

In conclusion the P3 is best for those who want a woofer with more sound quality features, while the L7 is best for those who want a woofer with more deep bass features. Both woofers are top-notch woofers within the car audio industry that will provide both bass and quality but will perform better when applied to their specific application.
