Rockford Fosgate P1 10" are the first in a family of world famous subwoofers called "The Punch". During their inception in the 1980's, they quickly became "The Woofer of Choice" for fanatic car audio systems, with a continued tradition today. Kevlar fiber reinforced paper cones deliver bass impact you can feel, and our VAST technology increases surface cone area up to 25%. Best in standard sealed and vented enclosures. Includes soft touch ABS trim ring. TECHNOLOGIES CEA-2031: Power handling on Rockford Fosgate speakers conform to CEA-2031 industry standards. Anodized Aluminum Voice Coil Former: Rockford Fosgate subwoofers use anodized aluminum voice coil formers that provide superior heat dissipation (up to 100° at full power levels). Unlike traditional plastic substitutions, aluminum acts like a heat-sink to quickly dissipate thermal build-up on the voice coil. This keeps subwoofers cool during high SPL conditions. Stitched Tinsel Leads: Improved reliability and performance by reducing fatigue and possible shorting.
