It is worth noting that each passive network is designed to work at a specific frequency for a specific speaker. Benefits of Passive Crossovers The switches on this passive crossover allow for attenuation. Active networks are often include other functions, such as remote level controls and bass boost circuits. Unlike passive networks, active crossovers can be designed to increase the level of the signal, but only in the case of powered filters. Active crossovers combine op-amps, resistors and capacitors to alter different frequency ranges of the signal. It works on line-level or preamp signals only. How an Active Crossover FunctionsĪn active crossover is a device that modifies an audio signal before the amplifier. Completely passive active networks have been available (but that was a long time ago). ![]() Some manufacturers include light bulbs, diodes or some form of positive temperature resistors to limit how much voltage a tweeter receives. Resistors are used to attenuate the output of devices, or sometimes used as part of a frequency-dependent impedance correction circuit called a Zobel network. The combination and configuration of these components are used to create a low-pass, high-pass or band-pass filter network. Four components are commonly used in passive networks: capacitors, inductors, resistors and protection devices. The behavior of these components attenuates portions of the signal going to the speaker itself. How a Passive Crossover Network Works This inductor is one of the pieces used in a passive networkĪ passive crossover network is a component or group of components that is installed on the speaker wires between an amplifier and a speaker. We are going to delve waist-deep into the benefits and drawbacks of the crossovers commonly used in car audio system component speaker sets. The purpose of a crossover is to split up the frequencies that pass through it. For this reason, we use three- and four-way speaker systems in most vehicles. A tweeter will self-destruct if you ask it to try to play bass frequencies. A woofer or subwoofer won’t be able to reproduce high frequencies accurately. To optimize the performance capabilities of a speaker, it should operate within the frequency range for which it was designed. ![]()
