The Alexander Bb/High F Model 107X is based on the innovative design of the Model 301 triple horn which was introduced with great success in 2003. Model 107X is the result of a goal we defined: To construct a descant horn that provides articulation and tone similar to that of a F/Bb double horn.
The elimination of the tuning bit in the mouthpiece receiver and the launch of separate leadpipes and bell branches allows independent tuning of each side of the horn. The articulation and sound of the high F horn is also more homogenous. The long leadpipe gives the Bb horn a fuller sound. The Model 107X also allows to add an F extension to the A valve in order to play the natural harmonics of the low F horn.
With this instrument Gebr. Alexander gives horn players a new tool that makes the change from a full double horn to the descant horn a comfortable one.
