Detail 01
17.50mm cup diameter
The widest in the Classic line. More lip vibrates, so the sound gets bigger and darker but takes more air.

Independent shopping perspective
Denis Wick's largest Classic trumpet mouthpiece, the 1X, in silver. Built for symphonic players who want a big sound and a very wide rim.

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 widest in the Classic line. More lip vibrates, so the sound gets bigger and darker but takes more air.
Detail 02
Extra wide. Spreads pressure across the lip for endurance, at the cost of some flexibility and fine control.
Detail 03
Open throat. Free blowing with more low-end body; you'll feel less back-pressure than on a standard throat.
Detail 04
Keeps the sound centered and even across registers rather than adding the extra edge a V-type backbore gives.
Detail 05
A large-bore heritage design, which is why the proportions run bigger than modern all-purpose pieces.
Detail 06
Cooler, slightly firmer feel on the lip than gold. Some players react to silver against skin over long sessions.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
The 1X is larger: 17.50mm cup versus 17.25mm on the 1, with a wider rim. Both use a 3.90mm throat and barrel backbore.
No. The large cup, open throat and barrel backbore push toward a broad symphonic sound. The V-type backbore models like the 5E or 3E are the screamer pieces.
It spreads mouthpiece pressure over more of the lip, which many players find easier over long sessions. You trade away some flexibility and precision in return.
It's a Bb-style trumpet mouthpiece. Confirm your receiver takes a standard trumpet shank, since cornet and flugelhorn receivers are different.
