Rockford Fosgate P1S4-12 (11P1S412)

Feel the Difference with 1 Punch

Sonic Electronix has the brand new 2011 model of the Rockford Fosgate P1S412 Punch Stage 1 Subwoofer. This woofer has a peak power rating of 500 watts and an RMS rating of 250 watts. Just like all Rockford Fosgate products, this subwoofer is built with quality and durability. The P1S412 features a high modulus kevlar reinforced paper cone with a high density NBR half-roll surround. The 10 AWG nickel plated push terminals with keep a secure connection at all times while resisting corrosion. The Punch Series 12" woofer also comes equipped with 2" 4-layer high temp voice coil, poly cotton spider, extended pole piece, bumped backplate, and a proprietary spider venting/cooling technique that helps keep subwoofer operating at a safe temperature. Once again, Rockford has made a top notch product at an affordable price.

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.

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.

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.
