With a larger .581”/.601” dual bore, the CEU511 has a more open feeling and broader sound than the CEU411. Additional upgrades include a spring-loaded third slide kick for instant intonation adjustment as well as an extended-pull fourth valve slide to facilitate low register intonation and an in-tune low B. The CEU511 is an excellent choice for a musician wanting the breadth of sound and improved intonation of a compensating euphonium without the increased weight or cost.

Outfitted with a hardshell ABS case and large-shank Bach 5G mouthpiece, the CEU511 comes with either a lacquer or silver-plated finish.
