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 in the Punch P1 woofer increases woofer surface cone area by up to 25%. Best in standard sealed and vented enclosures. Includes soft touch ABS tri trim ring.
