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
Slightly smaller than the series 4's 26mm, so the lips sit in a more compact, controlled setting.
Detail 02
Narrower rim than the 4. Less lip is supported, which sharpens articulation but asks more of your endurance.
Detail 03
Middle of the series. Controls how much air passes before back pressure builds; affects how the horn resists at volume.
Detail 04
Balanced blow. Not as focused or high-register-biased as the V-backbore on the 9.
Detail 05
Firmer, slightly more brilliant feel than gold plate, and cooler on the lips. Can irritate skin if you react to silver.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
The 4 has a wider 26mm cup and 6.72mm rim, aimed at a big, full sound and endurance. The 6 is narrower at 25.40mm with a 6.26mm rim for added clarity.
Yes. The 6 is built as the brass band size in the Steven Mead series, with the narrower rim specifically for clarity.
Not primarily. The 9, with its V-type backbore and 7mm throat, is the one designed for high register, projection and clarity.
Plating wears at the rim over years of playing, faster if your skin chemistry is acidic. Wipe it dry after sessions to slow it down.
