Crossover

Figure 8-3 Two-way crossover component.

Crossovers (see Figure 8-3) are used to divide the audio signal into
multiple bands appropriate for different types of loudspeakers or
loudspeaker elements. In QuickMAPs, 2-way, 3-way, and 4-way
crossovers may exist. Each of these crossovers may be implemented
using Bessel or Butterworth filters with 1st- through 4th-order slopes, or
Linkwitz-Riley filters with 2nd- or 4th-order slopes, or combinations
thereof.

Two-Way Crossovers

In the ISP-100, 2-way crossovers are implemented as shown in
Figure 8-4.
