SONOR Essential Force Sounds
The 6-layer birchwood shells are a superb foundation for SONOR Essential Force Sets. A hefty and dynamic sound – with accentuated mid-ranges and highs, and defined lows – are the hallmark of these shells. With high-gloss-lacquered natural wood surfaces, SONOR’s Essential Force really steals the show.
SONOR Essential Force Birch Shell Design
Birchwood shells deliver maximum strength, perfect curving and neutral tuning — thanks to tension-free cross lamination of the individual layers of wood (CLTF Cross Laminated Tension Free Process).
