Denis WickDW5286 Classic Series Tuba Mouthpiece in Silver 3XL
1/2
Independent shopping perspective
The Korena take
Tuba mouthpiece with a 31.25mm cup, wide rounded rim, and the largest throat in this range. Suits F tuba players who want comfort.
Strong match
Who this is for
- F tuba work in quintet, solo, or orchestral section playing
- Long rehearsals where rim pressure becomes the limiting factor
- Players chasing a dark, open sound over cutting brightness
Consider the trade-offs
When to look elsewhere
- Large BBb or CC contrabass tubas — the cup runs small for those
- Players who need tight resistance to hold pitch
- Beginners; the wide rim and big throat both cost air
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
8.78mm throat
The largest throat in this range. Very open blow, dark tone, and less back-pressure to lean on.
Detail 03
XL wide, rounded rim
Spreads mouthpiece pressure across more lip area. That's the endurance gain — it doesn't change the cup size.
Detail 04
Round cup shape
More cup-like than the funnel Helleberg cuts. Gives clearer attacks and a bit more edge under the darkness.
Detail 05
3XL versus 3L
Same 31.25mm cup and 8.78mm throat. The 3L has a normal rim; the XL is the wide, comfort-oriented profile.
Detail 06
Silver finish
Standard plated feel with slight grip on the lip. Keep it wiped down so it doesn't tarnish where it touches you.
Final check
Know before you order
- 01Confirm your receiver takes this shank before ordering — the numbered models use a smaller one
- 02Mouthpiece only. No pouch or case included
- 03A wide rim can mask bad pressure habits rather than fix them
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is the 3XL good for F tuba?
That's its main use. The 31.25mm cup fits the smaller bore, and the wide rim helps on the long, exposed passages F tuba tends to get.
02What does XL actually change?
The rim only. It's wider and rounder than the standard profile, so pressure spreads over more of your lip. Cup diameter, throat, and backbore stay the same.
03Can I use it on a CC tuba?
You can, but the 31.25mm cup is smaller than what large CC horns usually want. Expect less volume down low than a 1 or 2 size gives you.
04Will the big throat make me sound muddy?
It can if your air isn't behind it. The 8.78mm throat is the widest here — it trades focus for depth and needs steady support to stay clear.
