Denis WickDW4880B-SMU Steven Mead Ultra Series Baritone Horn Mouthpiece in Gold SM5U
Independent shopping perspective
The Korena take
Gold-plated Steven Mead Ultra baritone mouthpiece, SM5U size: 25.70mm cup, 6.30mm rim, 7.40mm throat. For established baritone players refining an existing setup.
Strong match
Who this is for
- Baritone players who want a freer blow than a narrow-throat piece
- Brass band players moving up from a stock mouthpiece
- Anyone who already plays a Steven Mead Ultra size and wants gold plating
Consider the trade-offs
When to look elsewhere
- First-year students still building embouchure on a stock mouthpiece
- Euphonium players — this is the baritone-horn version
- Anyone unsure of their receiver size; shank fit is not adjustable
What matters in use
The specifications, translated
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 02
7.40mm throat
Wider than the 6.66mm SM6U. Less resistance, more air passes through, easier volume at the low end.
Detail 03
6.26mm rim width
Narrower rim in this series. Less contact area, more flexibility and range access, less endurance on long sets.
Detail 04
V-type backbore
Conical taper rather than a straight bore. Shapes a rounder, less edgy response than a trumpet-style backbore.
Detail 05
Gold plating
A common choice for players whose skin reacts to silver. Slightly warmer, grippier feel on the lips than silver.
Final check
Know before you order
- 01Mouthpiece only — no case, pouch or brush included

Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my euphonium?
This is the baritone horn version of the Ultra series. Denis Wick makes a separate euphonium Ultra mouthpiece in medium and large shank. Check your receiver before ordering.
02How is the SM5U different from the SM4U and SM6U?
Cup diameter, mainly. SM6U is 25.40mm, SM5U is 25.70mm, SM4U is 26mm. The SM4U and SM5U share a 7.40mm throat; the SM6U is narrower at 6.66mm.
03Does gold plating change the sound?
The plating affects feel and skin comfort more than sound. Cup diameter, throat and backbore drive the response.
04Is this a step up from a stock mouthpiece?
It is a specific size rather than a general upgrade. It suits players who know they want a wider throat and a narrow rim.
