The OP says he bought the speakers used, there must have been a reason he checked the screws holding the drivers. Wouldn't be something the average speaker would have a problem with, and no you're not missing anything.
In my case with cabinets made of bamboo, I'm relatively certain the screws would fail before the bamboo would strip, the common MDF baffle needs to be handled with respect, it will certainly not do well with a heavy handed power driver.
Plenty of ways to skin this cat, the tee nuts are a good idea also, or you could also drill and tap for brass threaded inserts. You could fill the holes with JB weld, coat the screws with grease or vaseline, and screw them in once the epoxy first starts to set up (model airplane/helicopter builder here, I've done it many ways).
