A crossover divides the input signal into different frequency bands. This means that the audio signal is split into a high frequency signal and a low frequency signal. The high frequency signal is then sent to the tweeter(s) and the low frequency signal is sent to the woofer(s).
In-line crossover is a design which is used in speaker systems. The design is most commonly used in speaker systems that have a tweeter and a woofer. The tweeter and woofer can then be placed on the same side as the crossover.
Active crossovers are installed in the car’s stereo system. With an active crossover, there is no cabling required.
Passive crossovers are installed in your speaker’s wiring.
Crossovers are designed to divide an audio signal into two or more frequency bands.
“Crossover is an electronic filter, which divides an audio signal into several frequency bands, as well as routes the bands to different destinations.”
