Audio crossovers are electric filtration systems included in acoustic utilizations . A lot of individual loudspeakers are  not able to dealing with the totaldigital spectrum from very low to higher sound frequencies withacceptable relative sound level & absence of distortion .Which means most hifi loudspeaker systems use a mixture of loud speaker drivers each supporting a separate frequency band . Cross-over divide the audio signals into discrete frequency bands that will be individually delivered to loud speakers optimized for those sound bands. An active crossover is different from a passive crossover simply because the division of the audio signal takes place before the signal is amplified. Active crossovers come in either analog or digital designs. Very often digital active crossovers add extra processing to the signal, like, equalization, delay & limiting. The task of a signal crossover is to separate the audio signal into bands. Those are subsequently seperately refined leading up to all of them getting merged together again. Some examples are noise reduction for example in Dolby A noise reduction; high frequency exciters; multiband distortion; multiband dynamics for example de-essing, compression, limiting; and bass enhancement.
