Crossovers “split” the frequency band to send to different drivers. In a two-way loudspeaker, for example, a
low
pass
filter is used to remove high frequencies from the signal sent to the woofer, and a
high pass
filter is used to
remove low frequencies from the signal sent to the tweeter. The above screenshot shows a two-way crossover.
In a four-way crossover, the signal is split into four frequency bands:
In most plugins, each output channel has a high pass filter and a low pass filter, each of which can be set to one
of a range of filter types and slopes, or individually bypassed. Clicking on the bars labeled “CH1 Bandpass Filter
OUT1,” and so on displays the filter parameters for that output channel.
Unlike conventional analog crossovers, the flexibility of DSP allows a completely arbitrary mix of different filter
slopes and types. Filters can be set at any frequency, or even disabled completely. This allows maximum
flexibility in matching your crossover to the acoustic characteristics of the loudspeaker drivers that you are
using.
