What is Audio crossover?
[[File:125 Foto Weiche mit CD.jpg|thumb|Passive crossover.]] [[File:Active Crossover.svg|thumb|Active crossover.]] '''Audio crossover''' is an electric circuit that separates low and high audio frequencies in a signal. It is needed because very small [[loudspeaker]]s ([[tweeter]]s) would break if fed by low frequencies. Likewise, bigger speakers ([[subwoofer]]s) are not able to play higher frequencies purely. Audio crossovers are divided to '''passive''' or '''active crossovers'''. Typical components used with passive crossovers are [[capacitor]]s [[inductor]]s and [[resistor]]s. If passive crossover uses resistors to adjust [[loudness]], those generate heat. Instead, active devices typically use resistors and capacitors with other audioelectronic components and those typically don't consume so much [[electric power]]. Also, active crossovers are easily built to be adjustable. Still, that doesn't mean that using passive crossover means low [[quality]]. ==Other websites== {{Commonscat-inline}} {{tech-stub}} [[Category:Sound]] [[Category:Electronic circuits]]
