Seems like every recent visitor to my office here at the Univ. of Southern California exhibits an irresistable impulse to poke their index finger into the speaker port of my new "Quicksilver" G4 while asking "what's that?." To avoid a punctured speaker, I decided that a speaker grill (hint to Apple!) would be a very useful modification to the Quicksilver case. I liked the basic idea of the modification William Rivas made using the finger guard he cut from his power supply in "More Examples of Quicksilver G4 Fan Noise Reduction Mods", but I really wanted something a just little "classier" in appearance.
I remembered a scrap of copper screen that I've had lying around in a "junk" drawer for years. I cut off a piece of screen slightly larger than the speaker opening in the case and then painted it black with a permanent marker. There's no magic in the copper screen, it's just what I had lying around. Any screen material should work fine, or you could even use a scrap of cloth for that matter. For best appearance with the "Quicksilver" theme (or if you're a Raiders football fan), I recommend it be black.
To install, just open the case and press in on the two tabs that hold the metal shroud over the speaker.
Remove the shroud and there's the speaker. The speaker sits behing a circular "port hole" in the case.
Remove two screws holding the speaker.
And slide the screen between the speaker and case. Replace the speaker, its two screws, and shroud. My grill screen is held in place simply by pressure between the speaker case and the circular "port hole" in the G4 "Quicksilver" case. Another option would be shaping the screen into a kind of "bottle cap" that could be slipped over the back of the "port hole".
My final result looks like this. You can still see the silvery face of the speaker through the black screen, but errant fingers can't get to it any more!
