Oddly enough this is one thing i have not done A/B blind yet though i'm inclined to side with Alan's comments on the non-effect of the speaker cloth.
Sound is not exactly like hard wind rushing at your face. It is air related and pressure related but the speaker cloth, being as light as it is, should have a negligible effect on the sound pressure created by the drivers within the room.
That being said, i did see some heavier plastic grills with rather narrow holes on some Energy speakers. Now THAT would impede air flow immediately off the driver cone more significantly.

In subjective tests i cannot say i recall any big or noticeable difference between having the grilles on or off my Axioms. Being such a potentially subtle effect if any, i think only an A/B test could help to define it.
