Denis WickDW6880 HeavyTop Series Trombone Mouthpiece in Silver 5AL
1/2
Independent shopping perspective
The Korena take
Large-shank silver-plated trombone mouthpiece in 5AL, with a heavier blank. Suited to orchestral and section players wanting a full sound with a solid high register.
Strong match
Who this is for
- Orchestral and concert band trombonists on a large-bore horn
- Players wanting more core and stability than a standard-weight blank
- Moving up from a stock 6.5AL to something with more body
Consider the trade-offs
When to look elsewhere
- Small-shank horns — the large shank will not seat correctly
- Lead and commercial players who want a shallow, bright cup
- Anyone with a silver allergy; the plating is silver
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
25.73mm cup diameter
A moderate rim size. Roomy enough for a full low register without the endurance cost of a wide-open bass mouthpiece.
Detail 03
6.64mm rim width
A medium rim. Spreads pressure enough for long sessions without the sharp bite of a narrow rim.
Detail 04
7.30mm throat
A fairly open throat, so the horn blows freely and takes more air at volume.
Detail 05
Barrel backbore
A straighter taper past the throat. Produces a full sound with the high register staying resonant rather than pinching.
Detail 06
HeavyTop blank
Extra mass in the rim and cup wall. Slots feel firmer and the sound has more core, with slightly less flexibility.
Final check
Know before you order
- 01Check your receiver — this is large shank only, no small-shank fit.
- 02Heavier blanks feel different in the slots; give yourself a week to adjust.
- 03Silver plating wears at the rim over years and can be replated.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my trombone?
Only if your horn has a large-shank receiver, which is typical on large-bore tenor and bass trombones. Small-bore and most student tenors use small shank and will not fit.
02How does the 5AL compare to the 6BL?
The 5AL has a wider cup, wider rim, and a more open throat with a barrel backbore, giving a fuller sound. The 6BL is narrower with a V backbore and a crisper, more focused high register.
03What does HeavyTop actually change?
It adds mass around the rim and cup. Notes tend to center more firmly and the tone gains core. The trade-off is slightly less bend and flexibility between partials.
04Is the 5AL good for orchestral playing?
Yes. The barrel backbore and open throat give the full sound and resonant high register that orchestral and concert band writing asks for.
