F/Bb Double Horn · Model 102
The main advantage of the compensated double horn is the reduced weight. As the Bb horn is extended by the length of the F horn, less material is used for this model. Due to the special design of the horn, it is often supposed to have a high resistance which might be an advantage.
The compensated double horn is also available with an additional stopping valve (Model 102ST). By using the K-model construction, both models develop an almost full horn-sound on the f-horn as well.
