Some time ago, when moving houses, I dropped the M22 from the stand height. The cabinet tried to open a little in one of the edges.
When powered the speaker, the cabinet was vibrating and you could hear the rumbling noise at low frequencies and high volume, so I needed a fix.
As I was in another country, with no easy way to send back to Axiom for repair, I did braced the cabinet myself externally. Went to the local carpenter and found a not-so-ugly way to attach bolts and brace it very discretely, and problem solved.
Now I can run the speakers at their max performance and no noise from the cabinet. And to answer your question, its very unlikely that the inside components (xover, wiring, drivers) got any damage.
(those M22 are now in a room setup in my parents house, so not in sight for the public, so no one will ever see the fix!)
