On a much less impressive (though more acccessible, at least for those of us who don't get to tool around with space telescopes on a regular basis) a similar technique is actually pretty common in consumer audio applications.

A number of Apple devices employ this technique, like the new iMacs. I know the 2019 (and presumably, the 2021) 16" MBPs do: https://thenextweb.com/news/the-new-imacs-have-force-canceli...

It's popular in higher-end subwoofers. While not the cheapest solution, a whole host of design issues is solved by simply adding a second amplifier and a second driver firing in the other direction. https://us.kef.com/kf92-subwoofer.html

If I'm not mistaken a fair number of portable Bluetooth speakers use something similar. If you're hearing a surprising amount of rattle-free bass come from a device that seems too small to pull it off, there's a decent chance they're using dual opposed drivers.
