All SABIAN sets are “Sonically Matched” by our 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 XSR Promotional Set consists of 14″ XSR Hats, 16″ XSR Fast Crash, 20″ XSR Ride and a FREE 18″ XSR Fast Crash.
