A small speaker at the bottom sends sound in two directions before recombining as it comes out of the horn. ASU copyright The path of the sound can be lengthened on one side by pulling the slide like a trombone. ASU copyright This is about as far as you can pull it. ASU copyright This tube can be removed to change the speaker if needed. ASU copyright
