Bi-Amping
True bi-amping can also be
accomplished with an external electronic
crossover. See Figure 6. Even greater
dynamics can be realized with bandwidth
limited amplifiers. If you decide to bi-amp,
please follow the recommendations
below :
1)Use at least a 12dB/octave high pass
filter no higher than 1500 Hz on the
tweeters.
2)Use at least a 12 dB/octave low pass
filter no lower than 6000 Hz on the
woofers.
This “staggered” active arrangement
allows one full octave of bandwidth
between the amp’s active range and the
speaker’s passive range. This stagger
allows the purpose-designed passive
network to operate as intended. You will
gain the benefit of dedicated amplifiers
