question about thermionic 3 plans and bracing


Hello; I searched on "bracing" and found some great pictures of bracing that Wayne has done on the PI 4. The question is where does the 18 inches come into play as specified in the plans? It looks like two braces near the horn and two near the woofer. Plans say brace every 18 inches. How does the 18 inches relate to thermionic 3. My kit has been ordered and I am getting a jump on the cabinet making. Thanks for any ideas. Ray.
