The DX-Series Bahia Bass drumhead features a black vinyl surface that provides ultra-low bass tones with very little attack. The combination of a 7.5-mil bottom layer of Clear Mylar film and a top layer of a black 40-mil vinyl provides durability and produces a softer sound when played with sticks or mallets. Fits most major brands of Pandeiros, Tan Tans, Surdo drums and for extra punch use them on your Drumset Floor Toms.
