Low Frequency
Figure 70. Example – Low Frequency Crossover Setup
As shown in Figure 70, set output channel 1 for the low frequency driver. To make changes select a box
by touching it and use the volume control to change its value.
The low pass filter should be set to the upper crossover point of the low frequency driver which in this
case (for JBL 2632-T) is
350Hz .
If the manufacturer indicates a particular slope then use it. In this case, JBL didn’t list a slope so we
chose
24dB/octave .
Depending on the speaker, you may choose to add a high pass filter to block low frequencies. In this
case, we chose to put a high pass filter to
30Hz , to block frequencies below the lower capabilities of this
driver although this is not deemed necessary by the manufacturer.
Set the crossover ID for easy identification. Here we set the crossover ID for channel 1 output L which
identifies it as the low frequency output for channel one (1). This is only a label for easy identification
and does not affect the crossover itself.
