Taking Punch to a Higher Stage

Sonic Electronix is now carrying the brand new line of Rockford Fosgate Punch P3 Series Car Audio Subwoofers. The P3D4-15 Punch Series 15" Subwoofer has a peak power rating of 1200 watts and a RMS rating of 600 watts. This sub will produce some earth shaking bass and is constructed with an anodized aluminum cone and a vertical attach surround technique. This woofer is also equipped with a 2.5" Voice coil and a protective PVC textured magnet cover. Add some bumps in your trunk and enhance your cars stereo system with this Rockford Fosgate Punch Series Subwoofer.

While built on a long standing history of performance, the punch series woofers can deliver not only the output to satisfy you when you want it loud but maintain a level of sound quality for when you really want to "listen" to your music. Taking many design cues from the Power Series, Rockford Fosgate engineers continue to improve the Punch Series year after year making it one of the most sought after woofer lines for music and bass enthusiasts alike. With features like Dual tear & fatigue resistant poly-cotton spider for high strength and anodized aluminum voice coil formers to handle heat buildup in the motor structure under full power situations, these drivers are designed to perform.

 
Anodized Aluminum Voice Coil Former

Anodized Aluminum Voice Coil Former

By using an anodized aluminum voice coil former on their subwoofers, Rockford Fosgate is able to dissipate heat from the voice coil more efficiently. A hot voice coil can melt the adhesive bonds, which will lead to eventual subwoofer failure. The aluminum voice coil former acts as a heat-sink to dissipate thermal build-up on the voice coil cool during high SPL conditions.

 
CEA-2031 Rockford Fosgate Subwoofers

Conforms to CEA-2031

Rockford Fosgate has built this subwoofer to conform to the CEA-2031 loudspeaker power handling industry standards. This means that you can trust the subwoofer to have the capacity to safely handle the continuous (RMS) power rating. Having a CEA-2031 power handling is important when matching a subwoofer to an amplifier because the power ratings are accurate.

 
Rockford Fosgate Stitched Tinsel Leads

Stitched Tinsel Leads

To improve the reliability and performance by reducing fatigue and possible shorting, Rockford Fosgate has stitched the tinsel leads to the spider. The multipoint periodic stitching lead wires reduce the mass of the tinsel leads to spread the stress over a greater area. This improves the reliability and performance of the subwoofer.

 
Rockford Fosgate VAST Surround

VAST: Vertical Attach Surround Technique

In order to increase the surface area of the cone without causing any installation issues, Rockford Fosgate designed the Vertical Attach Surround Technique (VAST). By redesigning the manner in which the surround adheres to the basket, these speakers gain up to 25% more effective radiating cone area. This improves the nominal efficiency and maximum output.
