BI-AMPLIFICATION
A bi-amplified system normally consists of an active crossover and two amplifiers. The active
crossover divides the audio frequency spectrum into two ranges: frequencies below the crossover
point are directed to the amplifier driving the subwoofer(s), while all frequencies above the
crossover point are directed to the amplifier driving the mid-range/tweeters.
