Crossover

Figure 8-3Two-way crossover component.

Crossovers (see Figure 8-3) are used to divide the audio signal into

Custom crossovers

multiple bands appropriate for different types of loudspeakers or

other than those

loudspeaker elements. In QuickMAPs, 2-way, 3-way, and 4-way

available from the

crossovers may exist. Each of these crossovers may be implemented

crossover

using Bessel or Butterworth filters with 1st- through 4th-order slopes, or

component can be

Linkwitz-Riley filters with 2nd- or 4th-order slopes, or combinations

constructed by
