Remove the following screws securing the speaker enclosure to the rear case:

One 2.5 mm Phillips screw

One 1.5 mm Phillips screw

One 2.5 mm Phillips screw

One 2.7 mm standoff screw

Standoff screws are best removed using a standoff screwdriver or bit.

In a pinch, a small flathead screwdriver will do the job—but use extra caution to ensure it doesn't slip and damage surrounding components.
