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
Middle of the range — .046 above the smallest 5A4 and .030 below the largest 20. Neither crowded nor demanding.
Detail 02
No shallow cup or tight backbore biasing it toward high register, and no oversized cup asking for extra air.
Detail 03
The standard bore. The tighter 27 throat only appears on the a-backbore upper-register models.
Detail 04
Heavier blank than the Standard Series 14, which carries the identical .670 cup and 26 throat.
Detail 05
Costs well under the gold-plated heavyweight pieces. Cup, rim and throat dimensions are unchanged.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Same .670 inch cup, same 26 throat, same standard rim and backbore. This is the heavyweight blank, so the difference is mass, not dimensions.
It's the all-around model. Schilke points students toward the 13, which has a rounder #3 rim for quicker response and a C cup for volume.
Look at the 14A4a — similar .673 inch diameter, but a shallow A cup, semi-flat #4 rim and tight a-backbore for high work.
The dimensions that shape the playing — cup diameter, rim contour, throat — are identical. The plating and the price are what differ.
