Using a Phillips #2 Screwdriver, remove two 5mm screws from the speaker. The edges of the speaker are very thin and sharp and could cut your finger. The speaker will have a light coating of glue to hold it in place. A little force from your fingers will pull it right out. Remove the speaker and set it face-down on the table.
