When removing the speakers, it is likely the gaskets will become dislodged from the frame and the speakers and fall somewhere in between.

Make sure you have both gaskets and that neither are torn or otherwise damaged.

Pay attention to the alignment posts only on the top side. These ensure your gaskets are oriented correctly when reassembling.

When reassembling, make sure the wires on the speaker are towards the bottom to fit smoothly into this cutout without catching and risking any damage to the wires or gaskets.
