I imagine it would be a good thing if you could use some
closed cell foam or something like that put the brace/rod
under a reasonable amount of compression. Perhaps you
could take a square of mdf, drill a hole in the center,
and glue it to the inside of the back panel centered on the
woofer cutout. you could then put a thin amount of the foam
in the hole then tighten the woofer mounting screws against
rod/dowel going from the hole to the back of the driver.
You could judge the force adjusting the thickness of the
foam to make it snug without putting too much stress on
the woofer frame or the mounting screws.

As I said I haven't done this, but I do put four of the dowels
around the woofer cutout to localize the panel reaction to
the woofer acceleration.
