AQUARIAN PWT13PD POWER THIN SNARE BATTER The Power-Thin drumhead features an ultra thin layer of the Power Dot material on top. This special Power Dot covers the main playing area of the drumhead. The Power-Thin is extremely durable while maintaining an open, sustained sound. The difference is that they have dots stuck to the underside of the head whereas the new Power-Thin has the dot (made from a slightly thinner, newly patented material) stuck to the upper side.
