USING PASSIVE CROSSOVERS

A passive crossover is a circuit that uses capacitors and/or coils and is placed on speaker leads
between the amplifier and speaker. The crossover delegates a specific range of frequencies to the
speaker for optimum driver performance. A crossover network can perform one of three functions:
High-Pass (capacitors), Low-Pass (inductors or coils) and Bandpass (combination of capacitor and
coil).
The most commonly used passive crossover networks are 6dB/octave systems. These are easy to
construct and require one component per filter. Placing this filter in series with the circuit will
reduce power to the speaker by 6dB/octave above or below the crossover point depending on
whether it is a high-pass or low-pass filter. More complex systems such as 12dB/octave or
18dB/octave can cause impedance problems if not professionally designed.
