I read somewhere (think it was on one of these forums actually) that removing the front grill can add to the sound quality and make it seem much clearer. I've just tried it with a CD and tbh I noticed very little difference, if any. Does it make a difference or was it just a rumour I read? Also does removing the grill have any negative effect on a speaker (I'm thinking about dust or dirt perhaps)? If it doesn't then I will keep them off because they look cool As long as it doesn't make them sound worse, I'm not losing out on anything.
