Electrolytic Capacitors
Electrolytic capacitors, on the other hand, are a specific type of polarized capacitors designed to handle larger capacitance values. They are widely used when high capacitance is required, often in power supply circuits. Electrolytic capacitors consist of two conducting plates separated by an electrolyte-soaked paper or a gel-like electrolyte.
Are the non-polarized capacitors good enough for crossovers?
I assume you mean non polarized electrolytic; all crossover caps including poly are non polarized. This comes up every once in a while and makes for a long discussion sometimes. Some information is subjective and opinion based, some fact based, such as electrolytic caps have higher esr (resistance) and shorter life.
