Denis WickDW5880E Classic Series Euphonium Mouthpiece - Silver, 6BM
Independent shopping perspective
The Korena take
Silver-plated medium-shank euphonium mouthpiece in the 6BM size. For players wanting a clear high register and clean tone on a pre-1974 B&H or Willson horn.
Strong match
Who this is for
- Pre-1974 Boosey & Hawkes or Willson euphoniums taking a medium shank
- Players who lose clarity up top on a deeper cup
- Brass band or ensemble parts sitting in the upper register
Consider the trade-offs
When to look elsewhere
- USA or Japanese euphoniums — those need the small or large shank versions
- Players wanting maximum low-register openness; the 4AM is the wider, opener cup
- Anyone needing a large-shank receiver fit
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
25.40mm cup diameter
Narrower than the 26mm 4AM, so the lip has less area to control. Easier endurance, tighter center.
Detail 03
6.26mm rim width
Moderately narrow rim. Less cushion than a wide-rim piece, but more freedom to move between registers.
Detail 04
7.12mm throat
Slightly tighter than the 4AM's 7.38mm. Adds resistance you can push against instead of blowing through.
Detail 05
Medium backbore
Middle ground between focus and openness. Keeps the tone clean rather than spreading it out.
Detail 06
Silver plating
Standard plating finish. Some players react to silver on the lip; gold-plate is the usual alternative.
Final check
Know before you order
- 01Check your receiver first — shank size, not brand, decides whether this seats correctly
- 02Sold as the mouthpiece only. No pouch, case, or brush included
- 03Expect a break-in period; rim and cup changes take a couple weeks to settle
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my euphonium?
It's a medium shank made for pre-1974 Boosey & Hawkes and Willson instruments. For a USA or Japanese horn, look at the 4AY (small shank) or 6BY (large shank) instead.
02What's the difference between the 6BM and the 4AM?
The 4AM is wider at 26mm with a 7.38mm throat and barrel backbore, aimed at an open sound and focused low register. The 6BM is narrower with a medium backbore and clearer high register.
03Is this a beginner mouthpiece?
It's a classic euphonium size rather than a student-specific one. The narrower cup and medium backbore make endurance manageable, so it works for a developing player as well as an experienced one.
04Does it come in gold plating?
This one is silver. Denis Wick offers other finishes, but that's a separate part number.
