A capacitor passes a high frequency signal easily, but resists low frequency ones. While an inductor does the opposite: it pass low-frequency easily, and impedes high frequency. In fact, inside most speaker enclosures you'll find an inductor used on the woofer to pass the low-frequency energy to the woofer, while a capacitor is used with the tweeter to pass the high-frequency energy to the tweeter.The reason to use an inductor there is that it doesn't "consume" or "waste" the high frequency energy, it just blocks it from passing, so that energy can then pass through the capacitor, to the tweeter, instead.In general, the behavior of an inductor is the dual to that of a capacitor, so most functions that require one can be implemented by using the other, but in a different arrangement. But that's not always true.

Why capacitor is used as filter but not the inductor
