The Powerstroke X sets another new standard. Powerstroke X snare drumheads are constructed with a coated single-ply 14mm polyester film with a 2mm inlay ring for easy tunability and overtone control. These heads have great durability, attack, and volume for contemporary rock, funk and R&B applications. Tonally, the Powerstroke X snare heads are the perfect medium between Coated Emperors and Emperor X heads. They have a near perfect balance of focused midrange tone control for all different makes of snare drums.
