What matters in use
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 01
A shade narrower than the full M2 rim, which trims some of the effort on long, high-lying orchestral parts.
Detail 02
Standard depth rather than shallow. Gives you volume for tone across registers instead of biasing toward the top.
Detail 03
Opened up compared to a 27. More air moves through, so the sound stays big at full dynamics.
Detail 04
Adds resistance behind that open throat. You get something to lean on and the sound stays focused instead of spreading.
Detail 05
The plain M2 uses a larger Schmidt backbore with a shorter throat and feels notably more open than this.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Both are number 2 rim. The M2 has a larger Schmidt backbore and shorter throat for a more open feel. The M2D has a slightly smaller rim and a tighter Schmidt backbore.
The M2D runs a 24 throat with a Schmidt backbore. The M2C runs a tighter 27 throat with a Schilke C backbore, so it feels more compact and resistant.
The M series pairs a standard C cup with a tighter backbore, a combination that works on Bb or Eb. The M1D is the model specifically called out for both.
No. It's a standard-depth bowl cup built for full tone. For lead work, a shallow A cup like the 13A4a in the Standard Series is the right direction.
