Remo 15" CS Batter Drum Head ** Important Note on Size ** This item is described from the Manufacturers packaging to our best ability, please ensure that the model number is suitable for your drum as some were only made for specific drum models. Constructed with 1-ply of 10-mil film, Remo Controlled sound ('CS' for short!) are distinctly recognisable by their cute black dot in the centre of the head. Adding an extra 5-mil of thickness at the point of contact, the black dot focuses the sound whilst adding some extra durability to the head. Controlled Sound heads have a naturally open sound with many mid-range frequencies, much like an Ambassador, but with a bit more control. With Remo Controlled Sound heads, you get the best of both worlds in terms of sound and a slight increase.
