| I am sure it is different for every embouchure!
But in my experience, the rim is the biggest contributor. Right behind in the cup. A sharper rim can really allow for some sizzle. A deeper cup more of a fat sound. Backbore and throat do contribute, but IMO, to a lessor degree.
Fokus mouthpieces are interesting solution for questions like this. 4 main rim sizes and 5 different cup/backbore styles to choose from. You can get a 10.5 with a deep cup and open backbore. You can keep the backbore the same and try a different rim.
People have come to me and said I want to move from a 7C to a 1C (not as big of jump as it sounds). I often have them try a Fokus 3 AA, then maybe a 7 AA, or 3 P. It is eye opening.
You might look into the Fokus mouthpieces (they are a TM sponsor). You might find just the right rim/cup/backbore combo for you.
