A 19" freq crash cymbal from AAX line. FREQ design is an exclusive dual-lathing process that results in unique, intensely-cutting crashes that deliver quick bursts of hi-frequency tone, and fill the stage with big, open sound. Although most rock cymbals cut with focused high-pitched tone generated by the bell, the 17" SABIAN Freq Crash gets its boosted cut from the exclusive FREQ dual-lathing process.
