A two-ply coated drumhead manufactured using Aquarians’ vacuum process that eliminates air bubbles and wrinkles between the two plies. Remember that big, fat, bassy tom-tom sound you heard on classic rock and roll records? The sound you could never achieve on your own? Now you can! Performance II drumheads were designed for loose tuning for depth and punch without over-ringing. This drumhead is sealed around the edge to create that really deep sound on the toms.
