[QUOTE="TJ Cornish, post: 56834, member: 162"] Re: Mythbusting Andrew, forget the whole idea of "under-powering". The concept had at one time a tiny grain of fact, but has been overblown to be so incorrect that it's a worthless way of thinking. Speakers die in one of two ways: Overexcursion - too much voltage that causes the diaphram to be physically damaged by stretching or banging against something, and OVERPOWERING. Overpowering happens when the voice coil exceeds its thermal capabilities and breaks, melts, or deforms. It's true that a square wave has more average power than a sine wave with the same maximum amplitude, but as long as the driver in question can handle the heat load of the square wave, no damage will result. The logical followon to the deplorable concept of "under-powering" causing speaker death is the equally deplorable concept that "a larger amp is less likely to blow a speaker than a smaller one". The basic premise is that the same signal fed into a larger amp may not cause clipping, which would theoretically reduce the average power delivered to the driver. The practical reality is that any moron who allows their system to run into clip with a small amp is clearly looking for more than their system can deliver, and when given a larger amp, will only run that into clipping too - destroying the driver even faster than before.
