Originally this model was born after constructing a W 293 X with a Bb crook. But after comprehensive studies we recognized the potential of this idea. The higher resistance causes more safety in the high range which is not comparable with most of the current horns.
The high demand allowed us the most intensive trial period we ever did for a new horn design.
The result is a new double horn which is similar to other horns made in Germany in sound and resistance, but also sets new standards in safety and carrying the sound into the hall. You should try it!
