This lightweight AA Series Extra Thin Crash Cymbal is made with B20 bronze. Its explosive attack and a full response, coupled with a low overall volume, make this cymbal perfect for subtle accents or quiet rooms. Sabian AA Series cymbals including the thin crash cymbal feature a combination of musicality and energy for sounds that are bright, bold, and explosive. Secret-process bronze shaped under 75 tons of pressure delivers inner strength and outer energy.
