Understand crossovers

Work through filter handoff, overlap, phase, and what measurements should prove.

    Frequency response

    Frequency response shows how loud a speaker is at each frequency. It helps reveal balance, crossover behavior, box tuning, and room problems.

    Impedance

    Impedance is the electrical load the amplifier sees. It changes with frequency, so a speaker marked 8 ohms is not 8 ohms everywhere.

    Basic · Crossovers & filters

    Crossover

    A crossover splits audio between drivers. It is not a hard wall; drivers still overlap around the crossover point.

    Phase

    Phase describes timing between waveforms. Around a crossover, poor phase alignment can make two drivers cancel instead of sum.
