How to Restore Paper Speaker Cones
Speaker cones are surprisingly durable given that they are made from paper products. Nonetheless, accidental punctures and excessive sound damage speaker cones. Speakers are designed to move in order to produce sound, and the sound vibrations can eventually cause rips and tears in the speaker cone. Muddy and distorted sounds are symptoms of a torn speaker cone. The good news is that you can repair rips and tears as long as the speaker coil has not been damaged.
