Cup Diameter
The Denis Wick 3XL has a cup diameter of 31.25 mm compared to 30.00 mm on the Denis Wick 5L — a difference of +1.25 mm. A wider cup generally produces a fuller, darker tone but requires more air support.
Cup Depth
Both mouthpieces share a very deep cup depth, so the sound character from depth alone will be very similar.
Throat Diameter
The Denis Wick 3XL has a wider throat (8.78 mm vs 7.89 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.
