Farrukh:

Thank you very much for your compliments.

To answer your question, I made my tweeter pods with polyurethane foam, hand-sanded and formed to fit within the
inside of the mirror-mount point, near the front pillars.

Once built, I ported holes for the speaker-wire and then epoxy glued the pods to the doors; in so doing, the application is tight, vibration-free (well, tweeters are not exactly subwoofers, I realize). I lightly tacked the
DynAudio tweeter pods into their receptacles with a less aggressive adhesive, if/when I need to remove/replace/repair them.

Kind regards,
