Description

The Rockford Fosgate P1S4-12 (11P1S412) is a popular Punch Stage 1 subwoofer that features a 250 watt RMS rating and a 500 watt peak power rating. Like other popular products from Rockford Fosgate, the subwoofer features a durable, quality design. The subwoofer features a paper cone that is reinforced with high modulus Kevlar and it also has a half-roll surround that is high density NBR.

The 10 AWG push terminals are nickel plated, offering a secure connection all the time, while also resisting any corrosion. A 2 inch four layer high temp voice coil, bumped backplate, extended pole piece, and poly cotton spider are also featured by this subwoofer. The spider cooling and venting technique ensures that the subwoofer continually operates at a temperature that is safe.

Anodized Aluminum

The voice coil former is made of anodized aluminum, and this helps to dissipate any heat from the coil efficiently, preventing problems with melted adhesive bonds that can result in the failure of the subwoofer. The featured aluminum voice coil former dissipates the thermal buildup when high SPL conditions occur.

Users also appreciate the fact that the Rockford Fosgate P1S4-12 has been built to meet CEA-2031 industry standards, allowing users to trust the subwoofer to handle the RMS rating safely. Tinsel leads have been stitched to the spider by the manufacturer, which helps to improve performance and fatigue, spreading out the stress over a much larger area.
