Optimum Shell Measurement (O.S.M.)

SONOR implements a slightly narrow outside shell measurement for optimized head contact. This is a SONOR specialty, resulting in excellent tone, better sustain and controlled decay. All shells are formed by only using pressure from the outside in our special moulds.
SONOR ProLite shell design

SONOR cross-laminates shells for superior stability, sonically enhanced resonance and spectacular tone. The CLTF process is a result of years of research by SONOR craftsmen.
SONOR ProLite shell thickness

9 plies for tom toms, floor toms and snare drums = 4 mm + 2 mm Dynamic Edge reinforcement rings at the edges.
12 plies for bass drums = 6 mm + 2 mm Dynamic Edge reinforcement rings at the edges.
Dual Glide System

The DUAL GLIDE SYSTEM represents a snare strainer mechanism. The strainer mechanism features a technically perfected snare wire engage-and-release system, along with great adjustability and a solid look and feel.
