The Zildjian S Series Band 18 Hats are a pair of hand cymbals designed for versatile musical applications, from concert bands to indoor and outdoor percussion ensembles. These cymbals are made from B12 alloy, consisting of 88 percent copper and 12 percent tin, which creates a balanced frequency response across low, mid, and high ranges. The manufacturing process includes complete turning of the top and bottom sides, intense hammering for consistent sound response across dynamic ranges, and a brilliant finish that enhances sound projection with bright, shimmering tones. Developed through a comprehensive two-year research and design project at the Zildjian Sound Lab, these cymbals offer a modern tonal quality while maintaining the quality standards of the Zildjian brand. The 45.7 cm (18 inch) size provides substantial presence with high controllability for precise musical expression. The B12 alloy construction contributes to durability and reliable performance under various playing conditions. These cymbals are suitable for multiple music styles and ensemble configurations, providing musicians with a tool for expressive performances with consistent sound characteristics. The design focuses on practical musical applications where balanced sound projection and control are essential requirements. Cymbal mounts and pads are available as separate accessories to complete the setup for performance purposes.
