These timpani feature cambered hammered copper bowls and the pedal balance spring system. The hammered bowls in this series feature a squarer 'cambered' profile than conventional bowl designs. Benefits are ample volume, ideal timpani decay, and significantly improved mallet response. In addition to the 23-inch and 26-inch sizes, the lineup has been expanded with 24-inch and 27-inch sizes.

Specially designed hammering machines faithfully simulate the hand hammering process while eliminating the unavoidable inconsistencies of handwork. The goal was not only to improve efficiency, but more importantly to recreate the technique of master craftsmen. The result is bowls that exude hand-made warmth.
