They say that the main dis-advantage of an active crossover system, is that you need to buy more amplifiers. This is true, but also a lot of fun! We like amplifiers. Amplifiers are awesome, and more amplifiers are even awesome-er, right?
With an active system, you get to choose different amps for different jobs. One stereo amp each for the subwoofer, bass, mids, highs, etc. The common assumption is that since the midrange and tweeters don’t need as nearly much power as the subwoofer, then you can use a big 2000W amp on the subwoofer, and maybe just 50W on the mids and tweets, right?
Nope. Not exactly. You don’t need the power, but you still need the voltage! Transient spikes are the reason.
