The Sabian AAX Series Studio Crash Cymbal has a thin design and small bell for quick response and tonally full, glassy, shimmering accents. The AAX crash cymbal delivers pure, bright shimmering tones. Like stainless steel, AAX is cool, modern, and extremely efficient. Tap with your finger or thrash with a stick, Auto-Focus Response maximizes sensitivity, equalizes high- and low-pitch levels, and purifies sounds by filtering out conflicting overtones.
