In 2012, Zildjian modified their popular K Constantinople line of cymbals by adding 15" and 17" crashes as well as a 19" crash/ride cymbal. Along with rounding out their size options, Zildjian also incorporated a new hammering technique, used a new pin lathe on the top and bottom, and used a vintage-style cup on the crash cymbals. These features give the cymbal more overtones and nuance while maintaining the overall dark quality that the Constantinoples are known for.
