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
Mid-size for the Classic line, which spans 18mm down to 17mm. Wider cups favor low parts, narrower ones the high register.
Detail 02
Narrow. More lip contact freedom and easier slurring, but pressure concentrates in a smaller area on long sessions.
Detail 03
Controls how much air the mouthpiece lets through. Wider throats blow freer; this one sits mid-range for the series.
Detail 04
The taper behind the throat shapes resistance and how the sound centers as you push volume.
Detail 05
Built around a bigger, more open tone quality rather than the tighter European profile.
Detail 06
A feel difference more than a sound one. Some players find gold warmer and less slick on the lip than silver.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
5N is wider at 17.50mm with a 4.60mm throat; 7N is narrower at 17mm. The 6N sits between them at 17.25mm with a 4.50mm throat.
The N models use a narrow rim — around 3.85 to 3.93mm. The plain 4, 5 and 7 use a standard wider rim from 4.50 to 5mm.
It uses a standard French horn shank. Test the fit in your leadpipe — if it seats too deep or sits proud, the taper does not match.
It works if you want a fuller tone and get along with a narrow rim. If endurance is your limit, a wider standard rim like the 5 serves better.
