19 mm cup diameter
One of the widest in the range. More lip vibrates inside the cup, which fills out low notes but tires you faster.

What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
One of the widest in the range. More lip vibrates inside the cup, which fills out low notes but tires you faster.
Detail 02
A narrower rim than the 3, 4 and 5. Better flexibility and slurring, less cushion on long sessions.
Detail 03
Same throat as every Classic Series tenor horn model, so airflow resistance stays familiar if you switch sizes.
Detail 04
Conical taper rather than a straight bore. Rounder, darker tone that blends into a section instead of cutting over it.
Detail 05
Slicker and warmer against the lip than bare metal, and an option if silver plating irritates your skin.
Detail 06
Same 19 mm rim. The 2A adds cup depth for a richer sound; the 2 stays more open and direct.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Yes. Tenor horn is the British name for the instrument called an alto horn in the US, so this fits either.
The 3 has a 18.50 mm cup and a wider 6.07 mm rim, aimed at all-round band playing. The 2 is wider and built around low-register power.
Plating wears at contact points with use. Wipe it dry after playing and clean with warm soapy water rather than abrasive metal polish.
It is a specific choice, not a universal upgrade. It suits players who want low-register weight and a wider rim than a factory piece gives.
