The Hans Hoyer K10 F/Bb Double Horn is the newest innovation for the orchestra. The design was developed in close cooperation with Markus Wittgens, Principal horn in the Gurzenich Orchestra in Cologne and is a member of the Bayreuth Festival Orchestra.

The K10 has a well-orchestrated middle range and a greatly responsive low register. An unknown ease in the higher area is obtained with a light rotary valve set, a full-flow switch valve, and an individually adjustable mouthpiece receiver – a pleasant, well-balanced set up for any professional.

Mouthpiece position in the Horn’s lead pipe is critical:

For best response and articulation, each K10 is supplied with a selection of 6 different mouthpiece receivers to achieve a perfect fit with the most common mouthpiece shanks.

Go to our F.A.Q page for more information.

Each and every K10 undergoes a series of tests by Markus Wittgens personally before being packaged and sent to our customers.
