The Speaker Grille Quicksilver G4 is a collection of two covers designed to be aesthetic enhancements and protective devices for “Quicksilver” Power Mac G4s, which sport exposed speakers on their front panel. While previous Power Macs have had grille covers to protect the speaker transducer itself, recently manufactured models do not, exposing them to potential damage from children’s fingers or other objects that might get poked in the sizeable hole.
The grilles themselves are held in place by a gasket system that requires neither adhesive nor glue, so you won’t damage or alter your Power Mac by installing them, and you can switch covers easily.
