Condition & Setup

This refurbished horn is in excellent playing order and has been professionally serviced, set up, and play-tested. The lacquer remains bright and glossy overall, with fine scratches, light scuffs, and localized tarnish, oxidation, and handling wear around the valve and linkage section. A shallow crease is present on the upper outer wrap, and an acide bleed is visible at a ferrule near the leadpipe brace. The fitted case has minor wear near a handle attachment.

Who the 11DN Double French Horn Is For

The 11DN is suited to professional players, advanced conservatory students, and experienced ensemble musicians who prefer the direct response and centered tonal concept associated with a Geyer-wrap horn. Its medium-throat yellow brass bell offers a different playing concept from Conn's large-throat, nickel silver 8D, making the 11DN particularly relevant for players seeking clarity, projection, and an efficient orchestral response.

Common Questions About the C.G. Conn 11DN

How does the Conn 11DN differ from the Conn 8D?

The 11DN uses a Geyer wrap, a medium-throat yellow brass bell, and nickel silver mouthpipe and slide tubing. The 8D uses a Kruspe wrap, a large-throat bell, and all-nickel-silver construction. These designs offer distinct response, resistance, and tonal concepts rather than a simple difference in quality.

What does the reversible F/Bb configuration mean?

The change-valve configuration can be set so the horn stands in F or Bb when the thumb lever is at rest. This allows a technician to configure the instrument according to the player's preferred valve orientation.

What kind of player typically chooses the 11DN?

The 11DN is intended for an advanced or professional horn player who wants Conn's professional construction in a Geyer-wrap format. It is well suited to orchestral, chamber, solo, and conservatory playing where a centered sound and articulate response are priorities.
