Currently I just have some adhesive backed Sorbothane hemispheres as feet, but I would like to upgrade to adjustable threaded feet. To do this I would need to add threaded inserts to the base, but the concern I have is the Oticas are rather heavy and MDF is a soft material. So I worry they could just punch through the base especially if I'm repositioning them and the weigh shifts to just 2 or 1 of the feet as I move the speaker around.
Has anyone done this and how has it worked out? Are there any steps I could take to minimize that risk, or am I worried over nothing and MDF is stronger that I credit it for?
My lifetime woodworking experience includes building the NX-Oticas and a pair of Encores and that's it.
