Detail 01
.673 inch cup diameter
The widest in Schilke's Group I range. More lip sits inside the rim, so the high register pinches less than on a small cup.

SchilkeStandard Series Trumpet Mouthpiece - Group I, 14A4x Silver
1/8
Independent shopping perspective
The Korena take
Shallow-cup Schilke lead mouthpiece with the most open backbore in the line. For trumpet players working above the staff who want minimal resistance.
Strong match
Who this is for
- Lead and commercial playing that sits above the staff
- Piccolo trumpet, which the x-backbore was designed around
- Players who find tight a-backbore pieces too stuffy to blow
Consider the trade-offs
When to look elsewhere
- Orchestral and concert band work needing a deep, dark tone
- Students still building a sound; a C cup serves better
- Players wanting a small rim; 17.09mm is this group's widest
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 air volume to fill, so notes above the staff speak with less effort. You trade depth and body in the low register for that.
Detail 03
x-backbore
The most open backbore Schilke makes. It reduces resistance and opens the sound, which is why it suits piccolo trumpet.
Detail 04
Number 4 semi-flat rim
Flatter and wider than a round rim, spreading pressure over more lip. That is where the endurance on long sets comes from.
Detail 05
27 throat
Larger than the 26 throat on Schilke's standard models. More air moves through with less back-pressure behind it.
Detail 06
Silver plating
Standard mouthpiece surface. It does not change cup, rim or backbore dimensions.
Final check
Know before you order
- 01Trumpet shank only. A cornet receiver needs the cornet version of this piece.
- 02Give it two or three weeks; a shallower cup changes where your chops sit.
- 03Keep a deeper cup around for concert and orchestral playing.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my trumpet?
Yes, it uses a standard trumpet shank and drops into a standard receiver. It will not fit a cornet, which takes a shorter shank.
02What is the difference between 14A4x and 14A4a?
Same cup diameter and shallow A cup. The 14A4a has a tight a-backbore that adds resistance. The x has a large backbore that blows much more openly.
03Is this good for a beginner?
No. A shallow A cup rewards a developed embouchure. Schilke's 13, with a C cup and rounded number 3 rim, is what they list for students and developing players.
04Can I use it on piccolo trumpet?
Yes. The x-backbore was built for Schilke's piccolo trumpets, where it improves ease of playing and opens up the sound.
