Independent shopping perspective
The Korena take
Gold-plated Schilke 11Ax: a .650" shallow A cup with a 27 throat and the very open X backbore, designed around Schilke's piccolo trumpets.
Strong match
Who this is for
- Players who want a free-blowing, low-resistance piece in a small diameter
- Doubling onto piccolo trumpet with a familiar rim size
- Upper-register work where a shallow cup helps
Consider the trade-offs
When to look elsewhere
- Players wanting a big, round cornet tone — the 11E funnel cup does that
- Anyone on a budget; the silver-plated models are roughly a third the price
- Large-diameter embouchures; .650" is at the small end of Group I
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
A cup
Schilke's shallow cup. Brightens the sound and helps the upper register compared to the deeper C and D cups.
Detail 03
X backbore
The largest taper Schilke offers here. Much easier blow and a more open sound than the standard C backbore.
Detail 04
27 throat
Wider than the standard 26. Less resistance, which pairs with the open X backbore for a very free feel.
Detail 05
Developed for piccolo trumpet
The X backbore exists to open up a piccolo's sound. On other horns it will blow noticeably freer than a standard piece.
Detail 06
Gold plating
The premium finish in this series, and the reason for the price gap over the identical geometry in silver.
Final check
Know before you order
- 01Mouthpiece only — no pouch or case
- 02The very open backbore takes air support; thin sound usually means underblowing it
- 03The 11A is the same rim and cup with a standard 26 throat if this feels too open
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What does the X in 11Ax mean?
It's the backbore. The X backbore is larger than the standard C, improving ease of playing and opening up the sound, originally for Schilke piccolo trumpets.
02Why is this so much more expensive than the silver ones?
Gold plating. The cup, rim, throat, and backbore dimensions match the silver-plated version of the same model.
03How is it different from the 11A?
Same .650" diameter and shallow A cup. The 11A uses a 26 throat and standard backbore; the 11Ax uses a 27 throat and the large X backbore for a freer blow.
04Is this a good first Schilke?
It's a specialized piece. For a general starting point, the 11, 12, or 13 with standard cup and backbore is the more usual entry.
