[QUOTE="tinmanchris217, post: 6029484, member: 610505"] Bwahaha... WAS a healthy thread. *flush* The speaker's coil creates force based on the chang in current passing though it. In a healthy setup, the V_AC gives you a quantitative estimate of how strong that force is. When the cone stops moving momentarily, the force on the coil is already pulling the cone back, as is the spider's mechanical force. DC isn't causing this. DC on a coil will make it push out and stay out. Similar phenomenon, but not the same. During a hard clip, or a square wave, the coil under goes a push-hold-pull-hold cycle... which can cause heat to build up and possibly leakage/ripple. It can also damage soft parts, because the push and pull happen faster than during normal sine wave operation. That is the end of the similarities though, because it still cycles at a high rate (30-100 Hz). If it's extremely underpowered, you'd have to clip the living snot out of the amp to cause serious damage, from the above hard clip symptoms. [/QUOTE]
