The speaker's gasket is not reusable. During reassembly, follow this step to replace the gasket.

Use tweezers to peel off and remove all the old gasket from the frame and speaker.

Use a microfiber cloth and isopropyl alcohol to clean all the gasket's adhesive residue from the frame and speaker.

Before installing the speaker gasket, find its proper orientation on the bottom of the speaker—the large cutout on the gasket should go around the speaker grille mesh.

Remove the larger, clear liner from the gasket and use tweezers to carefully put the gasket into place on the bottom of the speaker.

To avoid touching the exposed adhesive, only grip the gasket by the outer edges of the liner.

Use your fingers or a spudger to firmly press the gasket into place to secure it with the adhesive.

Remove the remaining liner and put the speaker into place, making sure the speaker connector doesn't get stuck underneath.
