Detail 01
126 mm French-bead bell
This model uses the smaller bell size cited against the A4’s 140 mm bell.

Independent shopping perspective
Built as the lighter take on the A4, the A4LT reduces weight through its mouthpiece receiver, bracing, and valve section. Its 126 mm French-bead bell is smaller than the 140 mm bell cited for the A4. Players get the A4’s free response and large, concentrated sound in a horn described as open and lively. For a skilled musician, the lighter layout also supports more direct sound-color changes and nimble improvising.
