ROCKFORD FOSGATE (P2D2-8) PUNCH P2 8" SUBWOOFER WITH DUAL 2-OHM VOICE COILS Rockford Fosgate has always been known as "The PUNCH" and the P2 8" subwoofer certainly continues with the tradition. Kevlar fiber reinforced paper cones deliver bass impact you can feel along with VAST technology to increase surface cone area up to 25%. The P2 subwoofers perform best in standard sealed and vented enclosures. Includes diamond cut cast aluminum trim ring. Optional grille insert available. 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. VAST Surround - Subs: The Vertical Attach Surround Technique significantly increases a subwoofer's effective radiating cone area up to 25%. Klippel Verified: Klippel is a speaker certification program allowing us to deliver the best possible subwoofers. FlexFit Basket - Subwoofer: The slot mounted frame pattern allows fine-tuning of the subwoofer's mounting position.
