.675 inch (17.14 mm) cup diameter

SchilkeHeavyweight Series Trumpet Mouthpiece in Gold 15A4a Gold
1/2
Independent shopping perspective
The Korena take
Gold-plated trumpet mouthpiece on a heavyweight blank. Shallow cup and tight backbore aimed at lead and upper-register playing, not orchestral depth.
Strong match
Who this is for
- Lead trumpet in big band or commercial sections
- Players who lose the top of the register late in a set
- Anyone wanting the 14A4a idea with a slightly wider rim
Consider the trade-offs
When to look elsewhere
- Symphonic and legit playing that needs cup volume and a dark tone
- Beginners — a shallow A cup punishes an unsettled embouchure
- Players who want the horn to stay light and quick-responding
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
Shallow A cup
Less cup volume, so the upper register comes easier and the sound brightens. The low register loses fullness in exchange.
Detail 03
27 throat with tight a-backbore
Tighter than the 26 throat used across most of the line. More back pressure, which helps hold the top end together and slots notes firmly.
Detail 04
Number 4 semi-flat rim
Wider, flatter contact spreads pressure over more lip. Easier on your chops over a long night, at some cost in flexibility.
Detail 05
Heavyweight profile
Extra brass around the cup and shank. Feels more solid and steadier under pressure, and the thicker blank resists dents.
Detail 06
Gold plating
Slicker on the lip than silver. Some players like the glide, others find it slips once they're sweating under lights.
Final check
Know before you order
- 01Mouthpiece only at this price — no pouch or case
- 02The heavyweight blank shifts the horn's balance forward slightly
- 03A shallow cup exposes weak air support; expect a rough first week
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What's the difference between the 15A4a and the 14A4a?
Diameter only, effectively. The 14A4a is .673 inch, the 15A4a .675. Same shallow A cup, number 4 semi-flat rim and tight a-backbore. Pick by rim comfort.
02Is the heavyweight worth the extra over the standard 15A4a?
It buys mass and a more planted feel, not extra range. If you already know the 15A4a works for you, the heavyweight is a refinement, not a fix.
03Can I use this for orchestral playing?
It isn't built for it. The shallow cup and tight backbore brighten the sound and thin out the bottom. A C-cup piece is the tool for that chair.
04Does gold plating wear off?
Plating eventually thins where your lip sits and where the shank meets the receiver. Wipe it down after playing and it lasts a long time.
