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
Smallest cup in this line. Less lip vibrating means an easier top and better endurance, with a thinner low register.
Detail 02
Standard width. More contact area spreads mouthpiece pressure, trading some of the flexibility a narrow rim gives you.
Detail 03
The tightest here. More resistance to push against, which helps control at soft dynamics and caps you sooner at loud ones.
Detail 04
Same backbore across this range, so response and slotting stay consistent if you switch to another Classic size.
Detail 05
Firmer, grippier feel than gold. Standard for most players, but it bothers some people's skin.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Rim width. Both are 17mm cup and 4.50mm throat, but the 7N rim is 3.85mm instead of 4.50mm — narrower, with more flexibility and an easier high range.
It works, but the 5 is the one aimed at beginners. It has a slightly larger 17.50mm cup and a shaped funnel, which is more forgiving across the whole range.
It uses the standard French horn shank, so it fits normal single, double, and triple horn receivers.
Pick by feel and skin sensitivity, not sound. Silver grips a little more, gold is slicker and is the fallback if silver irritates your lips.
