Speaker grills on or off?

i own macaw who likes shreading speaker grills.

A macaw that attacks speakers? You need to trade it in for a Norwegian Blue parrot.

I personally don't like to stare into a big black speaker covers, I like seeing the woofers and the beautiful wood veneer. Soundwise I don't hear much difference.

Off, off, always off. I'm told this often leads to a divorce but hey, it leads to better sound.

I have never owned a speaker that I could hear a difference one way or the other. I had Harbeth's and the manufacturer recommended they be left on so I did. The wood on my current speakers (Daedalus) is so darn pretty I sometimes take off the grills just to admire the view but more often than not I leave on the grills and they sound just as wonderful. I think this is another one of those things that audiophiles can get twitchy about for no good reason.
