All SABIAN sets are “Sonically Matched” by Product Specialists in the SABIAN Vault. Rather than just take each cymbal off the shelf and put in a box, they are first tested individually and then for overall compatibility with the other cymbals in the set. This ensures you get a ready to go set up, straight out of the box. The HHX Complex Promotional Set consists of 14” Complex Medium Hats, 16” Complex Thin Crash, 20” Complex Medium Ride and a FREE 18″ Complex Thin Crash.
