24dB/Octave Active Stereo Crossover
How to Use the Crossover (con’t):
For Bi-Amping in a Single Enclosure (con’t):
The dispersion characteristics of a typical speaker and horn are illustrated below:
This chart illustrates different diameter cone loudspeakers and their typical dispersion characteristics:
As previously stated, system balance is very important. Check your speaker manufacturer’s specifications for the sen-
sitivity of each driver and balance the system as described on page 8 using pink noise and/or a Real-Time Analyzer
in conjunction with an SPL meter. Signal delays may be needed between the crossover and the power amps to cor-
rect driver offset (for example, between a cone type loudspeaker and a horn), to minimize any phase cancellations
around the crossover frequency (see the illustration on the facing page). Once properly balanced, the system will
need to be equalized.
