By the help of the K- and M- series the french horn player will be able to archieve different sound ideas with the same cup and rim diameter.
The M sereis is distinguished by a brilliant sound with clear timbre. It is made possible by a more round and flat cup.
In contrast, the somewhat deeper cone-shaped cup of the K- series supports a classic dark timbre. Furthermore the rims are more rounded.
This way, K- and M- models helpto meet the miscellanous demands of the french horn player.
