16mm cup diameter
The smallest diameter in this range. Less lip inside the cup means easier high notes and a more compact sound.

Independent shopping perspective
The 5X pairs the line's smallest 16mm cup with its widest 6mm cushion rim and a V backbore. Built for lead and jazz playing.

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
The smallest diameter in this range. Less lip inside the cup means easier high notes and a more compact sound.
Detail 02
The widest rim in the line. Pressure spreads over more lip, so endurance improves but fast lip slurs feel less agile.
Detail 03
Pushes projection and focus rather than the rounder, blended sound of the barrel backbores used on the 3C, 4C and 5.
Detail 04
Mid-size for this line. Keeps resistance up, which is part of what holds the high register together.
Detail 05
Slightly grippier feel than lacquer. It dulls from skin acids, so wipe it down after playing.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Same 16mm cup and 3.70mm throat. The 5X adds a 6mm cushion rim and a V backbore for projection; the 5 has a 5.30mm rim and barrel backbore for a traditional French cup sound.
Not quite. Denis Wick's screamer is the 5E — same 16mm cup, bright and crisp. The 5X trades some of that edge for rim comfort and high-register focus.
It is a trumpet mouthpiece and works on Bb, C, D and Eb trumpets. Cornet and flugelhorn use different shanks and will not accept it.
The wide rim is kind to endurance, but the small cup rewards a developed embouchure. In this line the 4B is the easier all-around starting point.
