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
Refers to the mass of the blank around the cup and shank. Rim and cup dimensions are unchanged from the standard model 15.
Detail 02
Right at the boundary between Schilke's Group I and Group II. Middle of the road, not a small or large rim.
Detail 03
Standard throat on this line. Only the shallow A-cup Heavyweight models, like the 14A4a and 6A4a, use the smaller 27.
Detail 04
No specialty rim contour or backbore. It is the baseline the lettered variants deviate from.
Detail 05
The price difference buys the heavier blank, not different playing dimensions. Same .674 cup and 26 throat as the standard 15.
Detail 06
Surface treatment only. Nothing about the rim contour, cup depth or throat changes with finish.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Cup diameter, cup shape, rim and throat are the same at .674 inch and 26 throat. The Heavyweight uses a heavier blank, which is what the price difference covers.
Schilke lists it as an all-around size with a free-blowing, clear sound. At .674 inch it sits between the smaller Group I sizes and the larger Group II sizes.
The 14A4a is .673 with a shallow A cup, semi-flat rim and tight backbore, aimed at upper register. The 15 has a standard cup and rim for general playing.
26. That is Schilke's standard drill on this model. Shallow A-cup pieces in the same series use a 27 throat instead.
