Brace each panel with a wedge shaped brace. The top and bottom braces are the same shape, and the side braces are the same as each other. Brace each flare panel against the side wall of the external cabinet that surrounds the midhorn. Also, preload the back panel with a rubber ball as shown below. The back panel will vibrate and make the midhorn sound resonant without it.
