Pondoro Posted February 24, 2021 Share Posted February 24, 2021 I believe there is some break in period for speaker cones. A woofer is made of paper or plastic or metal, paper has fibers, plastic or rubber or foam have long chain polymers. These fibers flex when the speaker vibrates. I’ve never looked closely at a metal speaker but I’ll bet it has polymers at the inside and outside edges. But imagine a woofer reproducing 80 Hz. It flexes 80 times in the first second! I think the break in period can’t be too long. Now I am very experienced with metal fatigue. Metal has no break in period. You can wear it out (automobile engines dominant end of life failure mode is sliding wear, and careful break in avoids stressing the engine until the lubrication system is running with full flow. You can loosen seals via wear (turbochargers and jet engines need careful break in to get the rotating seals just right). But for back and forth vibration metal either breaks or it lasts forever, depending on how hard you bend it. Or life ends with corrosion or an over stress situation. I don’t believe metal breaks in.
