Detail 01
24 throat
A larger drill than Schilke's standard 26. It passes more air, so the sound opens up rather than closing off at volume.

SchilkeSymphony M Series Trumpet Mouthpieces in Gold M150D Gold

Independent shopping perspective
The Korena take
Gold-plated symphony trumpet mouthpiece. The 150 rim with a bowl C cup and tight Schmidt backbore gives orchestral players real resistance to push against.
Strong match
Who this is for
- Orchestral and section playing where a centered, even sound matters.
- Players who want something to blow against, not an open feel.
- Long programs where a slightly smaller rim saves endurance.
Consider the trade-offs
When to look elsewhere
- Lead and commercial work — a bowl C cup lacks that edge.
- Players who dislike resistance; the open M-star models blow freer.
- First-time upgrades — this is specialist gear at a specialist price.
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
Tighter Schmidt backbore
Adds resistance behind the throat. That is what you lean on, and it keeps the sound from spreading when you play loud.
Detail 03
Standard bowl C cup
Rounder bottom than a funnel cup. Gives an even color across registers instead of favoring the top or the bottom.
Detail 04
150 rim diameter
Slightly smaller than the largest M-series rims, so it is easier to hold together at the end of a long program.
Detail 05
Gold plating
Slicker and warmer against the lip than silver, and the usual choice for players who react to silver plating.
Final check
Know before you order
- 01Standard trumpet shank — cornet and flugelhorn receivers will not take it.
- 02The tight backbore feels stuffy at first; give it a few weeks.
- 03Mouthpiece only, no pouch — budget for one if you carry it loose.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What is the difference between the M150D and the M150?
Same 150 rim. The M150 uses the larger Schmidt backbore with a shorter throat for a more open, freer feel. The M150D's tighter Schmidt backbore gives more resistance.
02Why pair an open 24 throat with a tight backbore?
The wide throat lets air through so the sound can grow, while the tight backbore behind it keeps that air focused. You get volume without the tone spreading.
03How is this different from the M150C?
The M150C uses a tighter 27 throat with Schilke's C backbore. The M150D keeps the wider 24 throat and puts the resistance in the Schmidt backbore instead.
04Is this suitable for a high school player?
It is an orchestral piece for players who already know what resistance they want. A Standard Series mouthpiece is the more sensible starting point.
