Yellowbird and everyone else- I love the speaker in the well cover trick! This might be totally stupid but what do you think about this idea? Instead of using the speaker grill, do you think I could get decent sound by cutting many holes in the well cover? Actually, I would use my laser instead of drilling or cutting, so the layout and size of holes would be uniform and symetrical and look really trick. But do you think that would muffle the sound too much?
