A passive crossover is an audio component that separates audio signals based on their frequency to be sent to the appropriate speakers (such as woofers, midranges, and tweeters) after the signal is amplified by an amplifier. This component uses passive electronic components such as capacitors, inductors, and resistors, and does not require an additional power source because it works using power from the audio circuit itself. #Vintageaudio #vintagestereo #hifiaudio #audiophile #audiophiles #class
