The 18" Sabian AAX Thin Crash Cymbal - Brilliant (21806XCB) introduces a whole new palette of sound to the AAX line. A small raw bell delivers faster response. A whole new style of AAX hammering, much more visible on the surface of the cymbal, makes for a thinner, more complex and slightly darker crash. At the same time, more highs are introduced into the sound, resulting in a wider band of frequency. For drummers, that means brighter highs and more complex lows.
