Distortion frequencies caused by clipping the woofer power
amplifier won’t reach the tweeter, so there is less likelihood of
tweeter burnout if the amplifier clips. In addition, clipping distortion in the woofer amplifier is made less audible.
■ Intermodulation distortion is reduced.
■ Peak power output is greater than that of a single amplifi er of
equivalent power.
■ Direct coupling of amplifiers to speakers improves transient
response—especially at low frequencies.
■ Bi-amping reduces the inductive and capacitive loading of the
power amplifier.
■ The full power of the tweeter amp is available regardless of the
power required by the woofer amp.
