Saving a Worn-out 'scratchy' Speaker

Overloading loud-speakers can damage the voice-coil and lead to a scatchy sound.
No need to scap them, here's a simple method of reviving them. And at no cost!
Supplies

Soft toilet or face tissue - unused.

Remove the case to reveal the speaker

Apply slight pressure with your finger (or something soft) to areas of the speaker cone until you find a spot and pressure that makes the sound clearer.

Carefully insert lightly crumpled soft tissue between the cone and the metal housing, adjusting to get the clearest quality sound.

Re-assemble the radio.
