how many of you actually prefer to leave the grills off of your speaker? i noticed that i get better sound from the speaker when i remove the grills, but im far too paranoid to leave them off. dust, moisture, debris all prevent me from staying with the idea of no grill. what do you guys do? and do you take any precations if you do indeed leave the grills off permanantly. personally i think speakers look far more attractive without grills.
