HHX cymbals, like their HH counterparts, are hand hammered by a Sabian cymbal maker in the factory. The HHX line has been modified from its HH roots by including Sabians "Tone Projection" design - youll notice much larger ridges and bumps on the bow of the cymbal. This design increases projection and spiciness, effectively creating a more modern version of the already dark HH sound. These cymbals work very well every musical style, putting the HHX series among the most popular cymbals on the market today.
