Bells for Ricco Kühn horns are made either from one blank and hammered by hand or they are made by a spinning process on mandrels of our own design. Bells made from a single blank are more expensive and require a great deal of experience. The material can be thinner and the whole bell is usually harder than their spun counterparts, depending on the manufacturing technique.
When the same metal and bell size is used, horns with hand hammered bells have a somewhat lighter response, are reacting more sensitive and admittedly, sound somewhat brighter in ff. Horns with spun bells have a somewhat higher but at the same time agreeable resistance, the sound is fuller and in ff firmer.
Both manufacturing methods have their advantages depending on model and bell size.
On some models, it is possible to supply bells with a gusset inserted. This even more expensive technology enables the production of hand-hammered bells that are almost the same thickness right up to the rim.
This means it is possible to make them with very thin walls and yet still retain sound stability in ff.
We have three sizes of horn bells, which we make in different thicknesses and designs depending on the model.
