Detail 01
0.988 in. (25.10 mm) inside cup diameter
A wide rim opening. More lip vibrates, which helps low-register power but tires an underdeveloped embouchure faster.

MarcinkiewiczSymphonic Bore Standard Tenor Trombone Mouthpiece 5F-S
Independent shopping perspective
The Korena take
A tenor trombone mouthpiece with a 0.988 inch cup and an open 0.234 inch throat. For players on larger-bore symphonic horns.
Strong match
Who this is for
- Orchestral and concert band tenor trombone with a large bore
- Players wanting more depth in the low register
- Anyone stepping up from a shallower student mouthpiece
Consider the trade-offs
When to look elsewhere
- Lead and commercial playing that wants a bright, shallow cup
- Small-bore jazz horns, where the open throat drops resistance too far
- Young students still building air support
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
0.806 in. cup depth
A deep cup relative to the bore. Darker, rounder core and easier low notes; upper register takes more work.
Detail 03
0.234 in. drill / venturi
An open throat. Air moves freely for volume and breadth, at the cost of the resistance some players lean on.
Detail 04
1.500 in. outside cup diameter
A wide, substantial blank. More metal mass around the cup, and a heavier feel in the hand.
Detail 05
3.170 in. overall length
Longer than a compact model, so it seats deeper in the receiver and can shift where slide positions sit slightly.
Detail 06
Compared to a Bach 15C
Use that as your reference point if you already know how a 15C feels — this sits in the same neighborhood.
Final check
Know before you order
- 01Confirm your receiver takes a standard large-shank tenor trombone taper
- 02The open throat needs steady air — expect an adjustment period
- 03Both 5F-S and 15-S appear for this piece; confirm before ordering
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my trombone?
It is cut as a standard tenor trombone mouthpiece. Check your receiver taper first, since a small-shank horn will not seat it correctly.
02How does it compare to a Bach 15C?
It is built as a counterpart to the 15C, so a player used to that piece has the closest reference point for rim feel and response.
03Is this good for jazz or lead playing?
The deep cup and open throat push toward a dark, broad orchestral sound. Lead and commercial work is usually better served by a shallower cup.
04Will it help my high range?
Not directly. A wide, deep cup with an open throat favors low-register body and volume; the upper register demands more from the player.
