4. Applications
Bi-amping splits a signal into upper and lower frequency bands, and then assigns each frequency band to separate speaker cabinets. A subwoofer typically takes the
low frequency range. By splitting the signal this way, the speakers work more eciently, and you can achieve a cleaner overall sound.
