crossover installation The system supports conventional wiring, Bi-wiring or Bi-amping using the supplied passive crossovers . While conventional (parallel mode) wiring will provide excellent sound, bi-wiring or bi-amping may further enhance the performance in no-compromise systems . Bi-wiring uses a separate pair of speaker wires for the high frequency and low frequency signal between an amplifier channel and its associated crossover network . This gives you the option of choosing wire whi
