Conn 10DYS Symphony Series Professional Double Horn - Lacquer

Designed for players who need projection, precision and modern flexibility, the Conn 10DYS Symphony Series double horn combines classic Geyer-style influence with CNC-level accuracy. Its all–yellow brass construction produces a warm, resonant tone that blends beautifully in orchestral and chamber settings, while the Schmidt-style small-throat bell adds focused projection that reaches the back of the hall without strain. A direct-soldered Geyer-taper mouthpipe gives the horn a quick, lively response under the hand, and the detachable bell offers practical portability for travel and storage. With reversible fourth rotor tuning, an adjustable finger hook, precision-milled mouthpiece receiver and a mouthpipe water key, the 10DYS delivers the control, comfort and tonal flexibility required for professional rehearsals and elevated performance.

Compact Projection and Responsive Feel With Geyer-Taper Design

Players looking for clear articulation and efficient airflow will appreciate how the 10DYS reacts to different dynamics and phrasing. Its direct-soldered mouthpipe improves resonance and reduces effort, making fast passages and sustained lines easier to execute cleanly. The small-throat bell helps maintain a compact, centered voice that projects through an ensemble without overpowering it, while the detachable bell preserves tonal focus with the added benefit of easy transport. Together, these features make the 10DYS a reliable choice for orchestral work, chamber playing and demanding repertoire that requires both power and subtlety.

With a reversible fourth rotor for F/Bb or Bb/F setup, durable string linkage, ergonomic hand placement and consistent CNC-machined components, the Conn 10DYS offers seasoned brass players a refined instrument built for clarity, comfort and confident performance season after season.
