The new Aquarian SKIII20 Superkick 3 Coated 20″ 1-Ply Batter Bass Drum Head with Power Dot features a narrow muffling ring. This narrow ring is approximately 1/2 the width of the ring used on Impact bass drum heads. This new ring allows the drumhead to produce more low-end, more punch and more volume than any other pre-muffled bass drumheads. The Floating Muffling System is made of felt for a pre-muffled yet natural sound. The felt moves and breathes with the drumhead. This drumhead sounds BIG!
