Rockford Fosgate has always been known as "The PUNCH" and the Punch P2D2-8 and P2D4-8 8" (20cm) subwoofers continue that tradition. The Kevlar fiber reinforced paper cones provide a noticeable bass impression and VAST technology increases the cone area by up to 25%. The P2 8" subwoofers are best suited for sealed and vented bass reflex enclosures. Includes diamond cut cast aluminum trim ring. An optional grille insert is also available.
