Cup Diameter
The Schilke 60 has a cup diameter of 29.03 mm compared to 25.50 mm on the Bach 5 — a difference of +3.53 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 Schilke 60 has a wider throat (7.94 mm vs 5.85 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.
