The filing confirms what Conn-Selmer had announced as a tentative plan in January. At that time, the company said it intended to transfer professional French horn production to its brass factory in Elkhart, Indiana, while moving production of tubas, sousaphones, and student and intermediate French horns offshore. Conn-Selmer describes itself as the largest manufacturer of band and orchestra instruments in the United States, with brands including Bach, Conn, King, Holton, Leblanc, Ludwig, and Selmer.
