Re: Stand alone electronic x-over??
It depends on the crossover you're planning to use. If your amp gives you all of the crossover features and frequencies that you want, by all means use your amp's crossover.
But most amp crossovers have a relatively narrow range of frequencies, no bandpass frequency, and invariable slope and Q settings. That's where an external crossover could come in handy. Some head units have all of these built in, too.
