[QUOTE="ahole-ic, post: 7069335, member: 619324"] You both had quite a bit of misinformation in there, but you were more right than him. He didn't understand clipping. Those are square waves that apply the maximum amount of power to the subwoofer, thus raising the average power the coil sees. The amplifier will have a maximum amount of voltage that it can apply. Since the voltage cannot go higher than that, but the gain can be turned higher, the wave just stays at this threshold much longer than it should. This applies the maximum amount of power during this entire time. It is very hard on the amp and the speaker. The voicecoil must rid itself of all of this extra heat. As the wave rises and falls, less power is applied than at the peaks. During an unclipped wave, maximum power is only applied for a very small amount of time when the wave reaches its peak at the top and bottom. For the rest of the wave, MUCH less power is applied allowing the voice coil to cool. When a wave is clipped, there is MUCH less time between peaks and less time to cool. So you see from this why clipped power is so hard on loudspeakers. You claimed that any sub could take any amount of unclipped power. That's simply not true. If the power applied is able to average out so that the subwoofer cannot cool itself faster than heat is applied, the shellac/glue will melt and cause the voicecoil to be destroyed. [/QUOTE]
