Original sentence: Active models are usually bi-amplified, which means that the sound signal is divided into low and high frequency components by a crossover, and then the low-frequency signals are routed to a woofer and the high-frequency components are routed to a tweeter or horn.Bi-amplification is done so that a cleaner overall sound reproduction can be obtained
Edited sentence: Active models are usually bi-amplified, which means that the input sound signal is divided into two parts by an active crossover, for low and high frequency components, both parts are amplified, and then the low-frequency part is routed to a woofer and the high-frequency part is routed to a tweeter or horn.Bi-amplification is done so that a cleaner overall sound reproduction can be obtained, since signals are easier to process before power amplification
