that vibration probably won't have anything to do with the grille...

diffraction is a when the sound from the driver reflects on the speaker's baffle, mostly this is an issue with the tweeter, this results in a noticable decrease in imaging quality. Today, however, this has nothing to do with the grille anymore, so don't worry about the diffraction...

btw, what was the 'vibration' you noticed? could you describe the sound?

and what the majority of people do is the least of the matters, it's what you think is best. Removing the grilles, or leaving them on is your choice.

listen to them with the grilles on and with the grilles off, and see what you like most, if you hear any difference at all. If you'd hear a difference, this will most likely be that with the grilles on, there might be slightly less high, and they could sound a bit 'muffled' (a really heavy word for the marginally small difference you could hear).

if you can't hear any difference at all, go for the looks. What pleases you most, grilles on or off?

Keep them spinning,
