Mark,

Thanks. I'm hoping that whatever is sticking out of the potting is the
part that is the least robust and most likely part to need replacement
if the speaker gets driven too hard. I'll call the mfg. tomorrow.

I've heard of resistors getting blown and needing replacement with
these speakers so that's what I assumed they were.

Those aren't resistors. Maybe some sort of self-resetting circuit protector.
