Some of the Audiophile terminologies
CROSSOVER :
Why do speakers NEED crossovers? Because very few drivers of any type - dynamic, electrostatic, or flux-capacitor - can reproduce the entire audible range with equal linearity. Crossovers allow a speaker designer to use multiple drivers specifically created for particular frequency ranges, a three-way design typically has a bass, midrange, and treble driver with one crossover circuit between the woofer and the midrange, and a second one between the midrange and the tweeter. - See more at: http://audiophilereview.com/reference-speakers/crossovers-are-evil.html#sthash.Prumo9Ut.dpuf
