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