Cup Diameter
The Schilke 16C2 has a cup diameter of 17.20 mm compared to 17.00 mm on the Bach 1C — a difference of +0.20 mm. A wider cup generally produces a fuller, darker tone but requires more air support.
Cup Depth
Both mouthpieces share a medium cup depth, so the sound character from depth alone will be very similar.
Throat Diameter
The Bach 1C has a wider throat (3.66 mm vs 3.65 mm). A wider throat allows more air through, increasing volume and projection but reducing resistance.
Which is better?
Neither mouthpiece clearly dominates the other — the right choice depends on your embouchure, playing style, and the sound you're after. Try both if possible.
