This was my attempt at humor. Guess some people are better at telling jokes than others.
I'm an experienced builder/servicer involved in performance upgrades. Yes, working with the holes in the frame does lower the drama and incident of involuntary speaker cone and/or cabinet modifications vs prying on the outside of the frame. Engaging a couple of threads on a bolt/screw seems to do the trick -- every time.
Thanks for the instructional video.
