Yep, If I was smart and had planned out the whole project in full, I would have eliminated the exposed edges completely by......mitering them too. My brother pointed this out to me as well. I generally "work pretty well on my feet" and just jump right into speaker projects making decisions and figuring it out along the way, maybe a quick sketch here and there. This time, I had gotten set on the idea of that rabbet before I had fully decided on the miters everywhere else. I will have to take a pic of what I'm talking about, there is no way I can explain the issue.Why would you have not done the rabbet on the baffle? (just curious) I figured you were trying to minimize the exposed MDF edge.
I may have to backtrack and glue a strip of MDF back into the rabbet I ripped. 😭
