I'm building the Fostex back-loaded horn for the FE166E. The plan calls for the side panels to constitute an exterior surface on the front (see link below). This causes the plywood edge to be in a somewhat vulnerable location. How do folks keep these from eventually splintering? Do you normally veneer Baltic Birch horns? Should I add some sort of trim on this exposed edge (note that the baffle extends from the front of the cabinet so this may not make a sonic impact).
