With further inspection of the tweeters under a magnifying glass, I simply could not identify a connection point. I assume the connections ran up through a pair of those holes but I can't confirm without completing dismantling the casing. I ended up locating some more HT25 components which arrived today.

Now I must decide if I try to pull the grill off of another tweeter, potentially creating the same disastrous/expensive result, or simply cut holes in the factory mesh grills and surface mount.

I additionally pulled the front end apart and got the wiring routed from the crossovers to the speaker pods. I mounted the crossovers to another slab of HDPE and plan to secure them under the right cubby cover.
