The Aquarian Performance 2 Clear Drum Head deliver that big, fat, low tom sound heard on countless classic rock and roll records. Performance 2 drumheads were designed for loose tuning to get the depth and punch with no over-ring. The Performance 2 heads are manufactured with Aquarian’s Vacuum Process which eliminates air bubbles and wrinkles between the two plies and sealed around the edge to create that really deep sound on the toms.
