[QUOTE="ciaonzo, post: 8644914, member: 607015"] The extra power comes in handy when dealing with the reactive nature of all the different components in the passive crossover, combined with the reactive nature of the drivers. They can pose difficult loads to the amplifier because of the multiple inductive and capacitive phase angles and the cost of that is a looser "grip" on the driver itself. A few watts will make most drivers sing, all the extra power goes mostly into controlling the circuit/drivers during the wildly varying waveforms and amplitudes that music is composed of. So you need a few watts to get going and a few more to get going louder, all the while having tens to hundreds on tap for the necessary dynamics. You basically have a direct grip on the driver in an active scenario, and this offers better control. [/QUOTE]
