Denis WickDW5880B-SMU Steven Mead Ultra Series Baritone Horn Mouthpiece in Silver SM4U
1/2
Independent shopping perspective
The Korena take
Silver-plated baritone horn mouthpiece in the SM4U size — 26mm cup, open throat. For players wanting a fuller, broader baritone sound.
Strong match
Who this is for
- Baritone horn players wanting more low-register breadth than a small cup gives
- Doublers moving from euphonium who want a familiar wide cup
- Brass band players needing volume without thinning the tone
Consider the trade-offs
When to look elsewhere
- Players with limited endurance who tire on wide cups
- Anyone whose horn does not accept this shank size
- Players with silver sensitivity — this one is silver-plated
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
Open throat. Takes more air and rewards good breath support with volume; less resistance to lean on.
Detail 03
V-type backbore
Gradual taper, generally giving a darker and rounder tone than a tighter backbore.
Detail 04
6.30mm rim width
Medium rim spreads pressure across the lip. Slightly wider than the SM6U's 6.26mm, which favors comfort over pinpoint articulation.
Detail 05
Silver plating
Slightly grippier feel than gold and durable, but can irritate players with a silver sensitivity.
Final check
Know before you order
- 01Check your baritone receiver accepts this mouthpiece before ordering
- 02Switching cup size changes embouchure feel — allow adjustment time
- 03The open 7.40mm throat needs solid air support to sound its best
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How does the SM4U differ from the SM5U and SM6U?
Cup diameter mainly. SM4U is 26mm, SM5U 25.70mm, SM6U 25.40mm. The SM6U also has a tighter 6.66mm throat and narrower 6.26mm rim.
02Can I use this on a euphonium?
It is a baritone horn mouthpiece. Euphonium players should look at the Steven Mead euphonium models in the matching shank size.
03Is a bigger cup better?
No. A wider cup broadens the low register but costs endurance and high-range ease. Match the cup to your playing demands.
04Does silver plating affect tone?
Plating mostly affects feel and skin contact rather than sound. Choose gold instead if silver irritates your lip.
