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.
Passive crossovers are directly dependent upon the speaker's impedance and component value for accuracy. When
passive crossover components are used in multiple speaker systems, the crossover's effect on the overall impedance
should be taken into consideration along with the speaker's impedance when determining amplifier loads. CAUTION:
