    active crossover and passive crossover

    I am very interested in car modification. Those who have a certain understanding of car audio modification may know the concept of active crossover and passive crossover, but it is not very clear to me. What is the active crossover and passive crossover?

    Re: active crossover and passive crossover

    Hi,

    Please do simple internet research on your own.

    in short (not complete infromation):
    * Active crossover is placed at input of the power amplifier
    * Passive crossover is placed at the output of the power amplifier

    For more information, please
    * first do an internet research on your own
    * elaborate your question
    * give (links to) documents you refer to

    Re: active crossover and passive crossover

    Do you know the function of a two-way speaker crossover network or circuit?
    It passes high frequencies to the tweeter but blocks low frequencies that will damage the fragile tweeter. The crossover also passes low frequencies to the woofer and sometimes blocks high frequencies that cause a woofer to Shriek.

    I have seen and heard many speakers with passive crossovers and also many sound systems with active crossovers and most (the ones designed properly) sound fine.
    Most cheap two-way car speakers use only one capacitor in series with the tweeter to prevent damage and the woofer is allowed to Shriek. Some of them sound fine.
