You are correct. This was a prototype for my new one, which is done now. I broke up two bass cabs and the mid in the picture that day. I break them because it gives me knowledge about the fixings and glue lines. I use a sledge hammer to vent my anger. At the moment, I'm pleased with the glue. I had complete sections of a bass cab that de- laminated leaving the glue lines in tact.
Peace and goodwill to all speaker builders
