Bi-Amping

NOTES ON BI-AMPING (CONTD.)

True bi-amping can also be accomplished with an external electronic crossover. See Figure 10. Even greater dynamics can be realized with bandwidth-limited amplifiers. If your 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 12dB/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 and retain the sound quality designed into the passive crossover.
